(Â鶹ÒùÔº) —Up until now, the invisibility cloaks put forward by scientists have been fairly bulky contraptions – an obvious flaw for those interested in Harry Potter-style applications.
(Â鶹ÒùÔº) —Michigan Technological University's invisibility cloak researchers have done it again. They've moved the bar on one of the holy grails of physics: making objects invisible. Just last month, Elena Semouchkina, ...
(Â鶹ÒùÔº) —New optical technologies using "metasurfaces" capable of the ultra-efficient control of light are nearing commercialization, with potential applications including advanced solar cells, computers, telecommunications, ...
A couple years ago, researchers introduced a new material that they said could make any object invisible to both radar and the human eye. Invisibility cloaking would have a major impact on defense technology, they explained, ...
Light is an oscillating wave of electric and magnetic fields. The way the electric field component interplays with the atoms in a material largely determines how light interacts with matter. With visible light, however, the ...
"Crysis 3" (Electronic Arts, for the Xbox 360, PlayStation 3, PC, $59.99) is a gorgeous game. Its creator, the German studio Crytek, has lived up to its promises that it will set a new benchmark for computer graphics. On ...
(Â鶹ÒùÔº)—When an earthquake strikes, damage to buildings such as nuclear power stations can worsen the catastrophe. Researchers from France's Institut Fresnel and the French division of Menard, a ground-improvement specialist ...
Thermoelectric devices—which can either generate an electric current from a difference in temperature or use electricity to produce heating or cooling without moving parts—have been explored in the laboratory since the ...
(Â鶹ÒùÔº)—Researchers have created a dc invisibility cloak made of a metamaterial that not only shields an object almost perfectly, but at 1-cm thick is also the thinnest cloak ever constructed, reaching the ultimate limit ...
An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors.
