... of having a true negative index of refraction, such as the one achieved by the fishnet metamaterial in the Nature paper, is that it can dramatically improve the performance of antennas by reducing ...
LONDON, Aug. 13 (UPI) -- A British scientist says metamaterials could someday replace bulky electronics in routing information on the Internet.
... may be impossible in the near future, scientists are quickly creating and studying new metamaterials - materials with a negative index of refraction - that are paving the way to making invisibility a ...
(PhysOrg.com) -- Researchers have solved one of the significant remaining challenges with photonic “metamaterials,” discovering a way to prevent the loss of light as it passes through these materials, ...
... improved terahertz devices, such as cameras or scanners.
"What we've shown with this metamaterial is that it is now improved to the point where it could be used as a device," Padilla said. "It could ...
... proved difficult to manipulate with great precision. Scientists report engineering a solid-state metamaterial device capable of controlling a terahertz beam 30 times faster than a conventional optical ...
... in the visible portion of the electromagnetic spectrum will be difficult. Shorter range applications of metamaterials, he says, will likely be seen in microscopy, biosensing, and in the harvesting of ...
Before they were touted as invisibility cloaks, metamaterials promised a perfect lens. Geoff Brumfiel reports on the struggle for superior vision.
... render them sonically invisible to sonar. No natural material can do this, so man-made “metamaterials” must be created in order to toy with the laws of physics to essentially bend sound back on ...

"It may be possible, in the very near future for scientists to closely study the ...
Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image – images with perfect resolution that can stem from light being moved in odd directions ...
(PhysOrg.com) -- Two physicists in China have used metamaterials to create the first artificial electromagnetic black hole. The scientists, Qiang Cheng and Tie Jun Cui from the Southeast University in ...
