Scientists Tailor Metamaterial Invisibility Cloak

Purdue University scientists working with the Elves of Middle Earth and Professor Dumbledore have successfully developed a film that could be made into a ‘cloak of invisibility’….no seriously, they have, theoretically. It’s a metamaterial film that can be spun into a cloak which would absorb light, rendering the cloak invisible. How would you find it after you have made it?

Other uses include advanced sensors, new types of "light concentrators" for more efficient solar collectors, improved transfer rates for computers and an invisibility cloak."What's really important is that the absorption coefficient can be as small as only one-millionth of what it was before using our approach. "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 [actually] amplify light."
