Gold rings create first true invisibility cloak - [gadgets]
05:32 AM EDT - Oct,03 2007 - post a comment

The cloak's concentric gold rings can steer light waves travelling along a surface around an object and straight on again as if it was not there
The world's first true invisibility cloak - a device able to hide an object in the visible spectrum - has been created by physicists in the US. But don't expect it to compete with stage magic tricks. So far it only works in two dimensions and on a tiny scale. The new cloak, which is just 10 micrometres in diameter, guides rays of light around an object inside and releases them on the other side. The light waves appear to have moved in a straight line, so the cloak - and any object inside - appear invisible.

The cloak was built by a team led by Igor Smolyaninov at the University of Maryland, and borrows some ideas from the first theoretical design for an invisibility cloak, published by Vladimir Shalaev from Purdue University, West Lafayette, Indiana, US, earlier this year. Their breakthrough comes just a year after US and British physicists created an invisibility cloak that worked in the microwave region of the electromagnetic spectrum. At that time, a visible light cloak was thought to be years away because of the much shorter wavelengths produced in the visible spectrum.
