cloaking device - Nature Materials experimentMany “invisibility cloak” efforts have been demonstrated, but all have reflected some of the incident light, making the illusion incomplete.

Now, scientists have succeeded in “cloaking” an object perfectly for the first time, rendering a 7-centimeter cylinder invisible to microwaves.

Microwaves are important in many applications, principally telecommunications and radar, and improved versions of cloaking could vastly improve microwave performance.

The illusion would be difficult to achieve with visible light replacing the microwave spectrum.
