Now, an invisibility cloak you can see

Device hides objects in visible wavelengths

3:31pm, August 2, 2011

The first invisibility cloaks that live up to their whimsical nickname have arrived.

Unlike previous cloaks, which manipulated specially polarized light or microwaves and infrared already invisible to humans, two new approaches bend ordinarily visible light. Disguised by one of these materials, an object could vanish before your eyes.

“If invisibility is the goal, eventually you need to build something that’s detectable by the human eye,” says Majid Gharghi, an applied physicist at the University of California, Berkeley.
