Material Absorbs all Light, Converts It into Heat
	The new metamaterial developed at Duke University and Boston College presents tiny geometric features that are able to absorb both the electric and the magnetic components of electromagnetic radiation, in specific frequencies of the microwave spectrum. "Three things can happen to light when it hits a material. It can be reflected, as in a mirror. It can be transmitted, as with window glass. Or it can be absorbed and tur ... [read more >>]

Old Invisibility Cloak, New Material
	All previous invisibility cloak projects claimed at some point in time that a three-dimensional optical light cloak can be built. I won't deny that this is true, although I haven't bumped into any invisible objects lately which leads me to believe that this attempt has failed. Now, a new three-dimensional optical cloak seems to be emerging from the University of California, but this time it’s already built, although some remain s ... [read more >>]

T-ray Sensors Get Better at Detecting Explosives
	If it's light manipulation, then we're talking about metamaterials. Researchers report to have improved the design of T-ray sensors with the help of a metamaterial that guides T-ray light across the surface of the detector. T-ray sensors are thought to become the next generation of explosive and poison detection devices, that emit and detect electromagnetic radiation in the far infrared wavelength. This particular e ...

"Electromagnetic Wormhole" May Make Us Invisible
	It is humankind’s never-dying dream, from the oldest myths to SF movies. Now, could the "electromagnetic wormhole" make us invisible? A team led by Allan Greenleaf of the University of Rochester has investigated a way to achieve this. The result would not be the classical wormhole, a theoretical bend in space and time acting like a shortcut, moving an object over vast distances. "Instead, once something entered one end o ...

Could We Turn Invisible?
	One day Harry Potter's magic could be child's play and people could wear lightweight, magical cloaks, the result of high-performance from the latest technologies rendering them invisible. A Swedish/Chinese team led by Zhichao Ruan, Min Yan si Curtis W. Neff, has made a theoretical analysis of a column-shaped invisibility cloak, finding that a cloak following perfectly the specifications could make the object (or wi ... [read more >>]

The Invisibility Tunnel
	The invisibility is descending from fiction and movies to reality. New measurements show how to build an electromagnetic "wormhole", an invisible tube from both sides, that allows the light to pass down the unseen center. The idea is based on the technology of the spherical invisibility cloak proposed in 2006. An invisibility cloak should be built of metamaterial, a thicket of metal rings or other elements that ...

Bending Light Into Invisibility
	The glass or plastic lenses in your eyeglasses redirect, or bend light into the right direction to focus it when your own eyes are no longer capable of doing so. When looking through a lens that is not fitted to your eye, the image looks distorted to a small angle, exactly like looking at a straw emerged half way in water that looks like it's broken. That is because a light ray striking the surface of the water at a 45-degree an ... [read more >>]
