Invisibility Cloaks Becoming A Reality

INVISIBILITY CLOAK devices, long out of reach except to the fantasies of science fiction, have moved within reach when researchers at Berkeley created a material that can control light’s direction of travel.

The breakthrough at Berkeley could lead to systems for rendering anything from people to large objects, such as aircraft and boats, invisible to the eye - this is still a ways off.

Researchers at the University of California at Berkeley, whose work is funded by the American military, have engineered materials that can control light's direction of travel.

This research follows the earlier work at Imperial College London that had similar results with microwaves. Like light, these waves are a form of electromagnetic radiation but the longer wave-length makes them far easier to manipulate. Underlying the work is the idea that bending visible light around an object will hide it. This gadget is an amazing piece of emerging technology.
