This new device, described June 7 in a manuscript uploaded to arXiv.org, works by redirecting light waves around objects inside it. But unlike other recently described cloaking devices built from ...

Although many electromagnetic cloaking schemes exist at different wavelengths, realizing a broadband visible wavelength device is hard. By relaxing the need for phase preservation inherent to most ...

Most current cloaking devices can fully conceal the object of interest only when the object is illuminated with just one color of light. However, sunlight and most other light sources are ...

If you're cloaking a green object, for example, the device shifts green light to the blue part of the spectrum so it can pass through, then reverses the process. With no green light to bounce off ...

Nature Nanotechnology - Optical cloaking: A phase compensation trick. A cloak is a device that makes objects invisible to an external observer.

Physicists Nicolae Nicorovici from the University of Sydney, Australia, and Graeme Milton, from the University of Utah, have proposed that devices called superlenses could be used to create a type ...

Scientists Create Real-Life Cloaking Device by Gene DellaSala — May 10, 2018. ... Basically the waves reflected from the metamaterial matched the phase of the reflected wave from the surface while the ...

Hanford, has developed a "cloaking device" that works underwater ... but as they did so, their phase matched those being reflected from the surface and the amplitude decreased slightly.

The cloaking device was constructed from two pairs of two commercially ... which forces the different colors of a broadband wave to travel at different speeds. The second is a temporal phase modulator ...

Designtex worked with about 50 different clients to test Casper in its beta phase. The most obvious applications are for technology and financial services firms, which deal in sensitive data.

The cloaking device was constructed from two pairs of ... The second is a temporal phase modulator, which modifies the optical frequency of light depending on when the wave passes through the ...
