Invisibility Cloak ENGAGE!

Okay, so you maybe wondering why I sound like an spandex-clad second-rate comic book hero or a hyper-obsessed Harry Potter fan. (and if you're not, you're going to find out why anyway). The answer is simple: researchers at UC Berkeley have developed two new "invisibility cloak" prototypes and I'm excited.

So how do these things work? Well, these microscopic devices (not yet implanted or woven into a cloak) are composed of specially designed metamaterials which, in turn, contain holes whose diameters are smaller than the width of rays of light in the visible part of the spectrum, which "smoothly shuttle light rays around them" wrote Dan Vergano in his article for USA Today. "Being able to bend light in unusual ways is important for applications that almost resemble magic," wrote physicist Ulf Leonhardt of Scotland's University of St. Andrews in an e-mail to Vergano.
