Berkeley Scientists Create 3-D Invisibility Cloak

Xiang Zhang, director of UC Berkeley Lab’s Materials Sciences Division, led a team of Berkeley and DOE  scientists that made an ultrathin “skin cloak.” The team used an irregular 3-D object the size of just a few biological cells to demonstrate the technique. When the 80-nm skin cloak, composed of blocks of gold nanoantennas, was activated it prevented lights waves from being reflected back, therefore making the 3-D object optically invisible.
