Invisibility cloaking illustrating how cloaking works using electromagnetic cloaking. On the left, electromagnetic waves, which could be light, scatter upon hitting the cylinder in the middle. On the ...

Researchers and engineers have long sought ways to conceal objects by manipulating how light interacts with them. A new study offers the first demonstration of invisibility cloaking based on the ...

Researchers at Purdue University may have created the first practical way to communicate with absolute secrecy by concealing messages in time using tricks of laser light and fiber optics. The ...

A “time cloak” that conceals events rather than objects can hide secret messages through a trick of light, making information invisible to all but the intended recipient. Like an invisibility cloak ...

Inspired perhaps by Harry Potter's invisibility cloak, scientists have recently developed several ways -- some simple and some involving new technologies -- to hide objects from view. The latest ...

The study, by researchers from Imperial College London, involves a new class of materials called metamaterials, which can be artificially engineered to distort light or sound waves. With conventional ...

Physicists Moti Fridman and colleagues at Cornell University (Ithaca, NY) have successfully demonstrated a time-cloaking device that can “hide” time for 15 trillionths of a second. In a paper ...

Muggles are another step closer to donning a real-life invisibility cloak, as scientists have developed a new technology that can make things invisible under the sun. Spectral invisibility cloaking ...

Researchers at Northwestern University have designed an invisibility cloak that can temporally hide objects for an indefinite period of time. Objects covered by this invisibility cloak wouldn't ...
