(Â鶹ÒùÔº)—A general property of magnetic fields is that they decay with the distance from their magnetic source. But in a new study, physicists have shown that surrounding a magnetic source with a magnetic shell can enhance ...
Researchers at The University of Texas at Austin have designed a simulation that for the first time emulates key properties of electronic topological insulators.
(Â鶹ÒùÔº)—Scientists are exploring better methods of camouflage, a so-called scientific invisibility cloak, and news has spread fast about a Canadian company with substantial claims on how far they have come with camouflage ...
A metamaterial invisibility cloak that can adapt to hide different sized objects is demonstrated by in Nature Communications this week. The findings represent a useful advance for more practical applications of metamaterial ...
A new approach to invisibility cloaking may one day be used at sea to shield floating objects – such as oil rigs and ships – from rough waves. Unlike most other cloaking techniques that rely on transformation optics, ...
In many respects, metamaterials are supernatural. These manmade materials, with their intricately designed structures, bend electromagnetic waves in ways that are impossible for materials found in nature. Scientists are investigating ...
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 ...
A new approach that allows objects to become "invisible" has now been applied to an entirely different area: letting particles "hide" from passing electrons, which could lead to more efficient thermoelectric devices and new ...
(Â鶹ÒùÔº)—Â鶹ÒùÔºicists in the Department of Mechanical Engineering at MIT have developed a new theory derived from calculations that suggest it should be possible to construct an electron cloaking device, similar in principle ...
A metal object can be made invisible with the help of ordinary plastic, Pekka Alitalo and Constantinos Valagiannopoulos, researchers from the School of Electrical Engineering, have shown in their study.
