Cloaking Device

In this 2006 video clip, Duke University researchers David R. Smith, David Schurig, and Steve Cummer discuss their work in "cloaking" an object by bending microwaves around it. Their device consists of 10 concentric rings of a copper-and-fiberglass metamaterial. While scientists are still far from cloaking an object in visible light, the Duke device is a first step toward that goal. Video: Duke University
