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

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 ...

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

To see an object is to detect the rail-straight rays of light that have impinged upon and bounced off it, and not to see any of the rays that come from the scene directly behind. To not see it ...

Some scientists seem to take their cues from science fiction or fantasy novels. Physicists in Texas have developed a method to make objects “invisible” within a limited range of light waves ...

Cloaking may not be just for Harry Potter. Scientists have made an object invisible. Not to the human eye, just invisible to some kinds of electromagnetic radiation.

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.
