Experts create invisibility cloak
By Paul Rincon
Science reporter, BBC News
A US-British team of scientists has successfully tested a cloak of invisibility in the laboratory.
The device mostly hid a small copper cylinder from microwaves in tests at Duke University, North Carolina. It works by deflecting the microwaves around the object and restoring them on the other side, as if they had passed through empty space. But making an object vanish before a person's eyes is still the stuff of science fiction - for now. The cloak consists of 10 fibreglass rings covered with copper elements and is classed as a "metamaterial" - an artificial composite that can be engineered to produce a desired change in the direction of electromagnetic waves.
Like visible light waves, microwaves bounce off objects, making them apparent and creating a shadow. But at microwave frequencies, the detection has to be made by instruments rather than the naked eye.

KLINGONS FTW!!!!!
