Invisible Technology:

In an article published by Wired magazine, it was stated that: “the U.S. Army is getting closer to mastering man-made “meta-materials” that can bend light around an object.”

According David Smith, a professor at Duke University: “A metamaterial is a material with unique properties that derive from its physical structure, not its chemical make up.”  Smith’s findings suggest that, in order to actually manipulate light, the surface of the material being used (for example, the material in an invisibility cloak) must be much smaller than that of the wavelength of light being used.  “The advances in nanotechnology are making it easier to create ever-smaller structures that can manipulate ever-smaller wavelengths,” said Smith.
