The concept of an invisibility cloak sounds like pure science fiction, but hiding something from view is theoretically possible, and in some very-controlled cases it's experimentally possible too. Now ...

Metamaterial-based electromagnetic cloaking encompasses a suite of approaches that steer, suppress or cancel the scattering of incident waves to render objects effectively invisible to detection. Two ...

Invisibility cloaking techniques have come with a significant limitation -- they need to be orders of magnitude larger than the object being cloaked. A team of physicists may have overcome this size ...

A new approach to invisibility cloaking may one day be used at sea to shield floating objects – such as oil rigs and ships – from rough waves. Unlike most other cloaking techniques that rely on ...

Transformation optics is a design paradigm that employs coordinate transformations to manipulate the paths of electromagnetic waves through engineered media. By prescribing how space is stretched or ...

Correcting article: There are several papers on cloaking buildings from earthquake waves. Thanks to Sebastien Guenneau for providing clarification. There is a paper by M. Farhat, S. Guenneau and S.

It’s easy to see a number of nefarious uses for devices that allow you to walk the earth undetected, from traversing the grounds of Hogwarts after lights out to liberating the contents of a nearby ...

WASHINGTON, April 19—Invisibility cloaks are seemingly futuristic devices capable of concealing very small objects by bending and channeling light around them. Until now, however, cloaking techniques ...
