Miniature invisibility cloak that can conceal 3-D objects by refracting light waves.

Scientists at the Berkeley Lab and UC Berkeley have created an invisibility cloak made from a thin material covered with millions of gold-plated antennae which wraps around an object and uses the antennae to divert light waves from its surface, rendering it undetectable to the human eye. Light reflects off the cloak as if it were reflecting off a flat mirror. Unlike the fictional character, the ultrathin cloak is real, and it successfully concealed microscopic 3D objects from detection in vis...
