Foraging Metamaterials: Labs Craft Invisibility Cloaks, Perfect Lenses and Nanostructures

An invisibility cloak developed by David Smith's laboratory at Duke University. Placing an object in the center makes it invisible to microwave radiation. The cloaking material splits the oncoming microwaves, guiding them around the object and recombining them on the other side. Since the microwaves do not interact with the cloaked object, an observer on the right or left of the object would not notice it was hidden.
