Theoretical Blueprint For Invisibility Cloak Reported

Such a cloak could hide any object so well that observers would be totally unaware of its presence, according to the researchers. In principle, their invisibility cloak could be realized with exotic artificial composite materials called "metamaterials," they said.
"The cloak would act like you've opened up a hole in space," said David R. Smith, Augustine Scholar and professor of electrical and computer engineering at Duke's Pratt School. "All light or other electromagnetic waves are swept around the area, guided by the metamaterial to emerge on the other side as if they had passed through an empty volume of space."
Electromagnetic waves would flow around an object hidden inside the metamaterial cloak just as water in a river flows virtually undisturbed around a smooth rock, Smith said.

This is kind of a rehash of the previous post, but speaks directly about the electromagnetic properties of photons. The experiment, on the whole, relies on the ability of photons to become something a little different (plasmons, which we will get into during another thread that is upcoming). This conversion allows for the light to travel seamlessly along a narrow layer along the top of the metallic surface.
