Forget Harry Potter and his "invisibility cloak" -- theoretical physicists in the UK and US have proposed a clever way of making objects invisible. It would involve surrounding the object by a ...

How to Make an Object Invisible A new theoretical design using nanowires provides a way to hide devices from visible light.

High-tech cloaking machines could render small objects invisible and perhaps improve military stealth technology.

He and his colleagues found that there is a trade-off between how invisible a cloaking material can make an object and the size of the object it can cover.

Mr Ergin's cloak was designed to make objects invisible to infrared light, but it paves the way for more advanced materials capable of cloaking objects in visible wavelengths.

Scientists at the University of Rochester in New York have shown off a method to make objects invisible (shown) using a system of lenses. Four lenses are aligned to make the cloaking device.
