The new 3D-printed cloak is designed to make objects invisible to 10 GHz microwaves, which are about 3 cm (1.2 in) in wavelength.

While one would hope to make an invisibility cloak that performs like the central image, it appears that basic laws of physics may cause a result more like that of the image on the right (Photo: B ...

Most invisibility cloaks under development actually make objects more visible overall, not less, scientists have revealed. This novel finding points to ways researchers can develop better ...

We have been reporting on invisibility cloaks since starry-eyed theorists managed to show that it was mathematically possible to design a structure that prevented electromagnetic waves from ...

No longer the stuff of comic books, researchers have achieved invisibility for the first time. A new study reveals how a group of scientists have successfully turned a cylinder invisible.

An illustration of the "invisibility cloak" in action. Dr. Luigi La Spada The demonstration is not quite on par with that seen in J.K. Rowling's wizarding world, but for mere muggles out ...

Previous invisibility cloaks tried to gently redirect the light around the object they were hiding – but this required using lots of material, making the cloaks far bulkier than the object they ...

Making a better invisibility cloak Date: November 11, 2012 Source: Duke University Summary: The first functional "cloaking" device reported by electrical engineers in 2006 worked like a charm, but ...

The great unappreciated weakness of invisibility cloaks is that they only make things invisible to human eyes. Or x-ray imagers. Or ultraviolet sensors, infrared image analyzers, echo-location ...

Russia has developed and deployed new camouflage technology for its troops that many have nicknamed “invisibility cloaks,” local news has reported. “This new ‘cloak-nevidimka’ is part of ...

Selling invisibility cloaks to the wider public is still very much a dream for Tidball. But the scenario he envisages if he does succeed hints at just how much work is yet to be done to make that ...

Before the invisibility cloak announcements around 2006, people widely assumed that perfect invisibility was impossible, so it wasn't really being explored.
