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 invisibility ...
As one of four fundamental forces in nature, magnetism is virtually everywhere in the world. Many technologies—hard drives, ...
Invisibility cloaks made of plastic can now be created at home using 3D printers, researchers show. The first clues that cloaking devices might one day become more than science fiction, a la "Star ...
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 audio ...
It's often a case of swings and roundabouts. If you save money by buying a house out of town, you spend more time and money commuting. If you really measure the momentum of an electron, you have no ...

9X heat superscattering just made stealth thermal cloaks more real
Heat has always been the hardest part of the spectrum to hide, yet a new experiment that boosts thermal scattering by a ...
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 invisibility ...
Do we really need invisibility cloaks like the one Harry Potter uses at Hogwarts to move around undetected? Apparently, we do. At least two projects are studying materials that can hide the objects ...
Scientists might be a step – a teeny tiny step – closer to developing that Harry Potter-style invisibility cloak of your dreams. Researchers at UC Berkeley have created a thin metamaterial that can ...
When it comes to invisibility cloaks, one of the trickiest problems is how to make the things. The materials of choice are known as metamaterials which are created by assembling a repeating pattern of ...
Sometimes everything can seem to happen at once. The new game in town is active invisibility cloaks (AIC), which use electronics and antennas to generate a cloaking field to hide an object. Two types ...
Researchers have devised an ultra-thin invisibility 'skin' cloak that can conform to the shape of an object and conceal it from detection with visible light. Although this cloak is only microscopic in ...
