MetaMaterials: First Demonstration of an Invisibility Cloak

A team from Duke University has successfully demonstrated the ability of a material - a "metamaterial" to warp specific wavelengths of light around an object.

"You cannot easily warp space, but you can achieve the same effect on electromagnetic fields using materials with the right response," Schurig continued. "The required materials are quite complex, but can be implemented using metamaterial technology.

While the properties of natural materials are determined by their chemistry, the properties of metamaterials depend instead on their physical structure. In the case of the new cloak, that structure consists of copper rings and wires patterned onto sheets of fiberglass composite that are traditionally used in computer circuit boards."
