Researchers have "cloaked" a three-dimensional object, making it invisible from all angles, for the first time.

However, the demonstration works only for waves in the microwave region of the electromagnetic spectrum.

It uses a shell of what are known as plasmonic materials; they present a "photo negative" of the object being cloaked, effectively cancelling it out.

Yeah, interesting stuff, read that earlier today while on lunch, won't be long now before we have Harry Potter style cloaks. :ph34r:

What if you misplace the cloak though? :D
