Making 3D Objects Disappear

A 3D illustration of a metasurface skin cloak made from an ultrathin layer of nanoantennas (gold blocks) covering an arbitrarily shaped object. Light reflects off the cloak (red arrows) as if it were reflecting off a flat mirror.- Berkeley Lab

Invisibility cloaks are closer than ever to being a reality. Scientists at Berkeley have fashioned a "skin cloak" out of blocks of gold nanoantennas to effectively render a small 3D object invisible. The scientists believe that upscaling the technology to macroscopic objects is just a matter of engineering.
