Making a better invisibility cloak
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 ...

University of British Columbia researchers have invented a safe, efficient technology to wirelessly charge electric vehicles using "remote magnetic gears" – and successfully tested it on campus service ...
(Phys.org)—Glancing at one's daily consumption of energy would lead to usage that is more reasonable and less greedy. Such a challenge gave birth to eSMART. This EPFL spin-off is in the process of installing ...
EU-funded scientists experimentally and theoretically validated technology for the future convergence of wireless and wireline communications into a common infrastructure.
(Phys.org)—Although quantum theory can explain three of the four forces in nature, scientists currently rely on general relativity to explain the fourth force, gravity. However, no one is quite sure of ...
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 ...
(Phys.org)—New hardware lets engineers maintain the plasma used in fusion reactors in an energy-efficient, stable manner, making the system potentially attractive for use in fusion power plants.
Black holes in distant galaxies can provide us with vital knowledge about our planet. Chalmers is currently building two new telescopes which, despite the fact they are directed out into space, will measure and map the Earth.
Understanding the phenomenon of blackbody radiation – electromagnetic emissions that play a role in a broad range of physical systems – is an important part of physics instruction at both the high school ...
The Office of Naval Research's (ONR) Electromagnetic (EM) Railgun program is evaluating the second of two industry railgun prototype launchers at a facility in Dahlgren, Va., officials announced today.
(Phys.org)—Researchers at the University of Southampton have developed a model which explains how the spin of a pulsar slows down as the star gets older.
Scientists at the National Physical Laboratory (NPL) and the University of Leicester have been commissioned by the European Space Agency (ESA) to investigate the feasibility of using dead stars to navigate ...
How do magnets affect things at a distance? How does the Sun heat our planet from 93 million miles away? How can we send messages across the world with our cell phones? We take these seemingly simple things ...
(Phys.org)—V3Solar has developed a new way to convert the sun's energy into electricity using traditional technology in a new way, and in so doing have discovered a way to get twenty times more electricity ...
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.
