Light Fantastic: Flirting With Invisibility

Increasingly, physicists are constructing materials that bend light the “wrong” way, an optical trick that could lead to sharper-than-ever lenses or maybe even make objects disappear.

Last October, scientists at Duke demonstrated a working cloaking device, hiding whatever was placed inside, although it worked only for microwaves.

In the experiment, a beam of microwave light split in two as it flowed around a specially designed cylinder and then almost seamlessly merged back together on the other side. That meant that an object placed inside the cylinder was effectively invisible. No light waves bounced off the object, and someone looking at it would have seen only what was behind it.
