(PhysOrg.com) -- Science fiction and fantasy tales are full of the ability to "cloak" characters with invisibility. Whether it is a spaceship with a cloaking device, or a young wizard with an invisibility cloak, the interest ...
Invisibility cloaks can make objects invisible not just to light in the visible part of the spectrum, but to many other physical excitations. These include acoustic waves, matter waves, heat flux, and infrared or ultraviolet ...
A device that can bestow invisibility to an object by "cloaking" it from visual light is closer to reality. After being the first to demonstrate the feasibility of such a device by constructing a prototype in 2006, a team ...

(PhysOrg.com) -- Science has taken one more step towards creating a true real-life cloaking device. Assistant Professor Andrea Alůin and his colleagues at the University of Texas at Austin have successfully created a ...
Physicists Moti Fridman and colleagues at Cornell University have successfully demonstrated a so-called time cloaking device that is able to “hide” time for 15 trillionths of a second. In a paper published on arXiv, ...
(Phys.org) —John Howell, a Professor of Physics at the University of Rochester, and his teenage son, have uploaded a paper to the preprint server arXiv in which they suggest that some common magicians' tricks could be used ...
The first functional "cloaking" device reported by Duke University electrical engineers in 2006 worked like a charm, but it wasn't perfect. Now a member of that laboratory has developed a new design that ties up one of the ...

When you knock on a melon to see if it's ripe, you are using sound waves to probe the structure of the material inside. Physicists at the University of Chicago were using the same concept to explore how sound waves travel ...
