Physicists in Germany claim to have found the first naturally occurring material that has a negative, rather than a positive, refractive index. The material -- a metallic ferromagnet -- is very ...

WEST LAFAYETTE, Ind. – Engineers at Purdue University are the first researchers to create a material that has a "negative index of refraction" in the wavelength of light used for telecommunications, a ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

Cambridge, Mass. - August 1, 2012 - In a vacuum, light travels so fast that it would circle the Earth more than seven times within the blink of an eye. When light propagates through matter, however, ...

SAN DIEGO — University of California, San Diego (UCSD) researchers have announced the physical realization of negative-index-of-refraction materials that have been predicted by theory. Such ...

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

If invisibility cloaks and other gee-whiz apps are ever to move from science fiction to science fact, we’ll need to know more about how these weird metamaterials actually work. Michigan Tech ...
