The spectral cloak operates by selectively transferring ... then light in the green range might be shifted to blue - so there would be no green light for it to reflect. Then, once the wave has ...

Invisibility cloak that 'bends light around itself' could be a reality in two years. By DAVID DERBYSHIRE FOR MAILONLINE Updated: 09:58 EDT, 21 August 2009 ...

This cloak can hide an object from red light at 700-nanometer wavelengths but fails at the shorter wavelengths of green and blue light, the researchers report in the June 1 Optics Letters.

Researchers have constructed an invisibility cloak capable of hiding a tiny object by altering the behavior of the light that hits it. This is the first invisibility cloak made out of ...

The cloak works by bending light around an object in the centre of a specially-designed glass construction to make it invisible to a viewer. The video of the disappearing animals had baffled some ...

A device that manipulates light to open up small gaps in time has crept toward implementation outside the lab. Detailed June 5 in Nature, it could soon improve security over fiber-optic lines or ...

Light tricks: Weaving an invisibility cloak. Bend light the wrong way and you can make things disappear. ... green and blue light (Physical Review Letters, vol 106, p 033901).

Scientists in Germany are experimenting with bending light waves to make 3-D objects appear invisible. A true invisibility cloak could be possible someday.
