Controlling and bending light around an object so it appears invisible to the naked eye is the theory behind fictional invisibility cloaks. It may seem easy in Hollywood movies, but is hard... Read more
“Our work demonstrates a simple and inexpensive approach to electromagnetic power harvesting,” Using inexpensive materials configured and tuned to capture microwave signals, researchers at D... Read more
The cloak that renders one invisible is a common element in mythology and fairy-tales, but new materials with surprising properties bring the idea closer to reality by providing novel... Read more
Duke University engineers have developed a novel sensor that is more efficient, versatile and cheaper for potential use in such applications as airport security scanners and collision avoida... Read more
Using a new class of artificial materials, scientists at Duke University have designed a sensor that compresses images far more efficiently than existing technologies like JPEG. The material... Read more
Produces significantly higher intensities of magnetic fields using the same amount of electricity By using exotic human-made materials, scientists from Duke University and Boston Coll... Read more
Invisibility cloak one step closer to reality Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about... Read more
Dramatically increasing the computer’s power and memory The merging of two technologies under development — plasmonics and nanophotonics — is promising the emergence of new... Read more
Able to conceal a burst of light as if it had never occurred Last year researchers at Imperial College London proposed that along with being used to cloak physical objects metamaterials coul... Read more
An undergraduate student has overcome a major hurdle in the development of invisibility cloaks by adding an optical device into their design that not only remains invisible itself, but also... Read more
For the first time, scientists have devised an invisibility cloak material that hides objects from detection using light that is visible to humans. The new device is a leap forward in cloaki... Read more
Force of Acoustical Waves Tapped for Metamaterials A very simple bench-top technique that uses the force of acoustical waves to create a variety of 3D structures will benefit the rapidly exp... Read more
A Harry Potter-style invisibility cloak is one more step closer to reality thanks to the work of a research team at the FOM Institute for Atomic and Molecular Physics (AMOLF) in the Netherla... Read more
