D.R.D.O. projects on Negative refractive index cloaking systems which may easily fetch funding as discussed early.
Development concerns the most economically feasible method for applying the facts or principles identified by research before a product goes into full scale production. Industry is aware that tomorrow’s profit depends to a large extent on today’s research and the fact that money invested now in R & D probably will not generate income for several years to come.
The commonest areas of research in the board sense are:
a) Pure Research
b) Applied Research
c) Product Research
d) Manufacturing Research
e) Materials Research
f) Market Research
g) Operations Research.
Pure Research or Fundamental Research refers to investigations undertaken primarily of the sake of knowledge itself. In this type of research, there is no consideration of commercial gains. The effort is directed towards learning the laws of nature or the detailed study of accepted theory in the light of development of new knowledge. The direction of any pure research is not specified in advance but is determined as the work progresses. Traditionally, Pure Research has resulted in ‘Breakthroughs’ which have been recognized by coveted awards like the Nobel Prize.
The top discoveries were as follows:
For the development of the LED laser, Nick Holonyak; Shuji Nakamura, blue laser; Robert Hall, first semiconductor laser. these technical developments all have had enormous practical value. LED lasers, for instance, are mounted in most grocery scanners and CD players. (15.9% of the vote).
? For studies of weird quantum properties, such as nonlocality, entanglement, decoherence, and atom optics (Alan Aspect, Serge Harouche, Anton Zeilinger, Charles Bennett, Anton Zurek, David Pritchard, Joerg Schmiedmayer, David Wineland, Peter Zoller). Experiments by these scientists tend to uphold all the counter-intuitive predictions of quantum mechanics, such as the idea that an atom can be in two places at the same time. (11.6% of the vote).
? For discovering graphene (Andre Geim and Kostya Novoselov). Discovered only a few years ago, graphene is a form of carbon consisting of one-atom-thick sheets. Already the subject is one of the most active in all of condensed matter physics because of graphene?s properties, such as its high conductivity and its great mechanical strength. many scientists anticipate graphene to play a massive role in electronics. (11.3% of the vote).
? For discovering and developing carbon nanotubes (Sumio Iijima, Cees Dekker, Phaeton Avouris, Charles Lieber, Thomas Ebbeson). Still another form of carbon list makes it onto the list. Carbon nanotubes are soda-straw-shaped tubes of carbon, sometimes only a billionth of a meter wide and a few thousandths of a meter in length. Like their flat-sheet cousin graphene, they too have useful properties. Carbon nanotubes can be prefabricated to be conducting of electricity or semi-conducting, and are excellent conductors of heat. they too are strong and might one day be used to make components for electrical devices. (10% of the vote).
? For predicting, discovering, and developing negative-index metamaterials (Victor Veselago, John Pendry, David Smith, Xiang Zhang, Sheldon Schultz, Ulf Leonhardt). Metamaterials are often structured from tiny components, such as tiny rings and rods. they produce novel optical effects. they are expected to find applications as lenses, in microscopy, and even in rendering some objects invisible, a process called ?cloaking.? (8.8% of the vote).
? For developing chaos theory (Mitch Feigenbaum, Edward Ott, saint Yorke, Celso Grebogi, Harry Swinney, Benoit Mandelbrot). Chaos is the science that describes how our knowledge of some systems in nature swiftly degrades. the weather is a classic example of a chaotic system. Even when we measure atmospheric conditions accuracy in many places, our capability to predict future weather remains poor. (8.4% of the vote).
For discovering and developing photonic crystals (Eli Yablonovitch, Shawn Lin, John Joannopoulis). A photonic crystal is to optics what a semiconductor is to electronics. A photonic crystal grants only light of certain energies to propagate. (5.9% of the vote).
For detecting the accelerating cosmic expansion (Adam Riess, Saul Perlmutter, Brian Schmitt). Measurements of distant supernovas has led astronomers to believe that the cosmic expansion of the universe is not slowing or reversing, but actually accelerating. (5.6% of the vote).
For discovering extrasolar planets (Alexsander Wolszczan, Dale Frail, Paul Butler, Geoffrey Marcy, Michael Mayor, Didier Queloz, David Lathan). the development of a supremely sensitive form of spectroscopy granted astronomers to detect (at first indirectly and later directly) the presence of planets around nearby stars. (4.7% of the vote).
For the discovery of the top quark (Paul Grannis, Mel Schocket, William Carruthers). Nobels have been awarded for the discoveries of some other quarks, so why not also the top? (4.4% of the vote).
Applied Research is primarily directed towards solving some specific problem which has a practical purpose. Typically applied research finds uses for results of Pure Research. Development of transistor, computer chips etc are examples of applied research. Applied Research is designed to solve practical problems of the modern world, rather than to acquire knowledge for knowledge's sake. One might say that the goal of the applied researcher is to improve the human condition.
Several researchers feel that the time has come for a shift in emphasis away from purely basic research and toward applied research. This trend, they feel, is necessitated by the problems resulting from global overpopulation, pollution, and the overuse of the earth's natural resources, global warming, etc.
Manufacturing Research is directed towards development of tools and equipment, handling devices, and methods of manufacture which can result in costs and increase productivity. Manufacturing research is carried out parallely with product research as the feasibility of product research depends on the feasibility outcome of manufacturing research. Fiber optics, Robotics, humanoids, Just In Time (JIT) manufacturing, etc have added new focus in the area of manufacturing research.
Materials Research is linked with both product research and manufacturing research as the discovery of new materials has impact on both. The jet and missile age has put great emphasis on materials research leading to success of many space programs. Superplastic steel has made possibility of casting complex shapes such as precision gears by eliminating the need of costly final machining and joining commonly required with very hard forged steel.
Materials research such as magnetic field ,light field ,temperature ,piezoelectric sensor related materials and special magnets has also introduced new materials such as plastics that can conduct electricity, that change color with changes in temperature, that degrade in sunlight without spoiling the environment, and superplastics from which automobile engines can be made. High-tech ceramics, which incidentally do not resemble traditional earthenware pottery, have been developed which are stronger, harder, lighter, and more durable than metals.
Marketing fecilities:With markets throughout the world becoming increasingly more competitive, market research is now on the agenda of many organizations, whether they are large or small. To conduct market research, organizations may decide to undertake the project themselves (some through a marketing research department) or they might choose to commission it via a market research agency or consultancy. Before undertaking any research project, it is crucial to define the research objectives.
Operations Research (OR) is focused on the application of information technology for informed decision-making. In other words, OR represents the study of optimal resource allocation. The goal of OR is to provide rational bases for decision making by seeking to understand and structure complex situations, and to utilize this understanding to predict system behavior and improve system performance. Much of the actual work is conducted by using analytical and numerical techniques to develop and manipulate mathematical models of organizational systems that are composed of people, machines, and procedures.
Development: Development is concerned with the most economically feasible method for applying the facts or principles identified before a product goes into full scale production. Development is carried out typically after applied research which itself is completed after related Pure Research. For the chemical industry, evolving a new process technology from bench scale laboratory studies to pilot plant or semi commercial plant and then scaling up to a full scale commercial plant is an example of development.
Pay Back Period (PBP) which is the number of years required to recover the investment is often used for R & D project evaluation. P = I / O where P is pay back period in years, I is Rupees invested in R & D project, O is uniform annual return from project in Rupees per year. For example if Rs 120,000/- is needed for a R & D project which is expected to generate Rs 30,000/- per year, then Pay Back is 120,000 / 30,000 = 4 years. If risk factors in terms of probability of success for various R & D project alternatives are available, then the pay back period can be suitably estimated
An overview on current trends in stimulated Brillion scattering and Raleigh scattering optical phase conjugation is given.
CITATION: Phase conjugation can be done to have negative refractive index with self adaptive polygon squeezing by selective frequency/wavelength by difference in frequency modulation using dimensional squeezing method
This report is based on the results of the “Second International Workshop on stimulated Brillion scattering and phase conjugation” held in Potsdam/Germany in September 2007. The properties of stimulated Brillion scattering are presented for the compensation of phase distortions in combination with novel laser technology like ceramics materials but also for e.g.,phase stabilization, beam combination, and slow light. Photorefractive nonlinear mirrors and resonant refractive index gratings are addressed as phase conjugating mirrors in addition.
For OFDM systems, it is shown that the lower bound is maximized by placing the known symbols periodically in frequency. For single-carrier systems, under the assumption that the training symbols are placed in clusters of length (2 + 1), it is shown that the lower bound is maximized by a family of placement schemes called QPP- , where QPP stands for quasi-periodic placement. These placement schemes are formed by grouping the known symbols into as many clusters as possible and then placing these clusters periodically in the packet. For both OFDM and single-carrier systems, the optimum energy tradeoff between training and data is also obtained.
The meta-material All light or other electromagnetic waves are swept
around the area, guided by the metamaterial to emerge on the other
side as if they had passed through an empty volume of space." For a
total invisibility effect, the waves passing closest to the cloaked
object would have to be bent in such a way that they would appear to
exceed relativity's light speed limit. Fortunately, there's a loophole
in Albert Einstein's rules of the road that allows smooth pulses of
light to undergo just such a phase shift.The device's meta-material.The tiny
structures embedded in the metamaterial would have to be smaller than

Phase conjugation can be done to have negative refractive index with self adaptive polygon squeezing by selective frequency/wavelength by difference in frequency modulation using dimensional squeezing method says Sankravelayudhan Nandakumar: Specially designed linear dispersive media with one absorption line and one gain line the Sommerfeld precursors of a pulse can be amplified leading to an earlier detection of the signal. Also, we can show that in some systems with one strong absorption line, a carefully placed gain resonance must induce a discontinuity in the imaginary part of the frequency by cloaking with dependent index of refraction and in the first derivative of its real part.
The invisibility effect would work only for a specific range of wavelengths as invisibility effect would work only for a specific range of wavelengths. That means it operates only over a narrow range of frequencies," Pendry said.

The microchip digital logics may involve a frequency or wave length concept by involving row and column matrices by 8/16 selections of cloaking and uncloaking algorithms.This can also be used later for radiation therapy applications to shadow the radiations at specific spots.This also later could be used for astrogenetc corrections.Raleigh and Brillion scattering phase conjugated corrections as well for space signal corrections.This means that no meta -materials should be removed from the moon by rovers as this will retard the brain activities of humanbeings ,by controlling acoustic effect during any heating act a timer correction.
The metamaterials have been plagued by a major limitation: too much light is "lost," or absorbed by metals such as silver and gold contained in the metamaterials, making them impractical for optical devices. By finding is fundamental to the whole field of metamaterials it's feasible to conquer losses and develop these materials for many applications. The materials made of a fishnet-like film containing holes about 100 nanometers in diameter and repeating layers of silver and aluminum oxide. By etched away a portion of the aluminum oxide between silver layers and replaced it with a "gain medium" formed by a colored dye that can amplify light. By placing the dye between the two fishnet layers of silver, where the "local field" of light is far stronger than on the surface of the film, causing the gain medium to work 50 times more efficiently. The NIM is active in a range between 722 nm and 738 nm. At a wavelength of 737 nm, the negative refractive index improves from -0.66 to -1.017, and the FOM increases from 1 to 26. In a wavelength range around 738 nm, the FOM is expected to become macroscopically large, on the order of 106.
Unlike natural materials, metamaterials are able to reduce the "index of refraction" to less than one or less than zero. Refraction occurs as electromagnetic waves, including light, bend when passing from one material into another. It causes the bent-stick-in-water effect, which occurs when a stick placed in a glass of water appears bent when viewed from the outside. Being able to create materials with an index of refraction that's negative or between one and zero promises a range of potential breakthroughs in a new field called transformation optics.
Possible applications include a "planar hyperlens" that could make optical microscopes 10 times more powerful and able to see objects as small as DNA; advanced sensors; new types of "light concentrators" for more efficient solar collectors; computers and consumer electronics that use light instead of electronic signals to process information; and a cloak of invisibility. Excitement about metamaterials has been tempered by the fact that too much light is absorbed by the materials. However, the new approach can dramatically reduce the "absorption coefficient," or how much light and energy is lost, and might amplify the incident light so that the metamaterial becomes "active by self adaptive polygonal phase conjugation by Bose Einstein lasers by controlling the wave lenth/frequency. We can even have amplification of light instead of its absorption. Here, for the first time, we showed that metamaterials can have a negative refractive index and amplify light. Devise a way to deposit just the right amount of dye mixed with an epoxy between the silver layers of the perforated film. You can't deposit too much dye and epoxy, which have a positive refractive index, but only a thin layer about 50 nanometers thick, or you lose the negative refraction. Involve creating a technology that uses an electrical source instead of a light source, like semiconductor lasers now in use, which would make them more practical for computer and electronics applications.
A timer cloaking by frequency reversal dynamics:By taking advantage of the properties of periodic systems, physicists have described how to efficiently time-reverse ultrashort electromagnetic pulses. Since a time-reversed pulse evolves as if time runs backwards, time reversal eliminates any distortions or scattering that occurred at earlier times, regardless of the medium the pulse has propagated through.
The band structure of a photonic crystal supports pulse propagation in opposite directions, as indicated by the red arrows. Scientists have described a scheme that uses this band structure to time-reverse pulses with 100% efficiency. This can also be possible with frequency reversal dynamics.
The new scheme opens the way to the efficient reversal of truly few-cycle pulses with devices that are easy to fabricate and implement. It is based on dynamically tuning the wave speed in photonic crystals that contain “zero gaps,” which are band gaps with a zero width. As the scientists explain, band gaps are energy or frequency regimes where waves cannot propagate, and are a common characteristic of periodic systems such as photonic crystals. When a band gap has zero width, an incident pulse can propagate through almost perfectly instead of being reflected.
“The zero-gap structure has two features says Sankaravelayudhan Nandakumar “First, it serves as an effective homogeneous medium, in the sense that it admits the entire incident light; a standard photonic crystal, with a finite gap, would reflect most of the pulse. Second, the existence of two bands at close proximity allows one to transfer energy between them using relatively slow modulations using required metamaterials by frequency or wavelength modulations by this method of time-reversed electromagnetic pulses.
Using Xenon diflouride-bismuth gas mix-up spiral dynamics: The experimental realization of atomic Bose–Einstein condensation at ultracold temperature has led to rapid advances in creating and manipulating cold molecules, and which has given birth to a new research field of quantum matter-wave superchemistry. Contrary to the classical Arrhenius law, the tunneling dominated ultracold reactions can be realized through the highly-controlled magneto–optical technique. Novel quantum effects have been identified in these cold reactions, such as the super-selectivity rule in dissociating triatomic molecules, and the quantum size (vessel-shape) effect. In this review, we focus on a variety of new achievements in this fascinating matter-wave wonderland, including the quantum finite number effect and double-slit interference in assembling cold molecules, the quantum noise in triggering collective abstraction reaction, and the magnetic phase transition in a laser-catalyzed quantum spin-mixing gas. The practical applications of matter-wave superchemistry are also introduced, such as the optical information storage via quantum photo-association, and the laser-enhanced creation of spinor or even chiral molecules.
By building shrinking algorithm device:
By controlling how light bends around researches can build a shrinking device that makes objects appear smaller than they actually are. Although the original object does not actually shrink, the illusion of the smaller object is convincing enough to confuse viewers since the real size of the object cannot be perceived which can be used as signal security The shrinking device, the radius of this space is always positive. But as the radius approaches zero, the shrinking device becomes a perfect invisibility cloak.
Undesirable harmonics can be suppressed: by using phase winding cloaking systems may be possible and Rydberg electron collection fast tracking power outputs may also be possible.
By the variation of thermal diffusion energy mode algorithms by heating the refractive index could be controlled by Bose Einstein lasing as a function of differential heating algorithm that could be developed by producing oscillatory refractive index .using piezo electric acoustic control by producing steady state thermal diffusion mode which may also act as timer cloaking.
Conclusion: The properties of stimulated Brillouin scattering and Raleigh scattering properties are presented for the compensation of phase distortions in combination with novel N.R.I induced laser technology using sperro magnetic inductions as well as for para-ferromagnetic curie effect combinations using N.R.I. doped ceramics materials but also for e.g.,phase stabilization, beam combination, and slow light. Photorefractive nonlinear mirrors and resonant refractive index gratings are addressed as phase conjugating mirrors in addition. Finally a self adaptive polygon squeezed negative-positive phase conjugated correcting mirror proposed.
