Physicists Make Objects Invisible without Metamaterial Cloaking
A team of physicists has managed to make homogenous cylindrical objects completely invisible in the microwave range without relying on metamaterial coatings. The method is…
New ‘Cloaking’ Device Uses Ordinary Lenses to Hide Objects
Using a combination of four standard lenses, researchers at the University of Rochester have developed a “cloaking” device that hides objects when you look at…
Engineers Demonstrate Active Electromagnetic Cloaking
By surrounding an object with small antennas that collectively radiate an electromagnetic field, engineers demonstrate active electromagnetic cloaking. Invisibility cloaking is no longer the stuff…
Duke University Creates “Perfect” Microwave Cloak
Scientists have been able to successfully cloak an object, rendering a centimeter-scale cylinder invisible to microwaves. Many different invisibility cloaks have been demonstrated, but all…
Time Cloak Creates Hole in Time, Makes Events Disappear
The General Theory of Relativity by Albert Einstein implies that gravity can cause time to slow down. Scientists have now shown that there is a…
