Theoretical Blueprint for Invisibility Cloak

Using a new design theory, researchers at Duke University’s Pratt School of Engineering and Imperial College London have developed the blueprint for an invisibility cloak. Once devised, the cloak could have numerous uses, from defense applications to wireless communications, the researchers said.
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.”
