Invisibility Cloak For Computers To Beat The Heat!
A new variety of #-Link-Snipped-# should pretty much ward off the heat from hot devices. An article on the Optics Express speaks of such a possibility, about a theoretical cloak that can protect an area from extreme temperatures. #-Link-Snipped-#
Study author Sebastien Guenneau, of the French National Center for Scientific Research and the University of Aix-Marseille, states that the satellites could be wrapped in a thermal cloak, as it could prevent the satellites's overheating issue when it enters back the atmosphere. So far, a majority of invisibility cloaks have been developed from metamaterials that escort light waves about a certain region of space, fainting anything that lies in sight. Identical cloaks have been developed to misinterpret the trajectory of sound waves.
In the recent study, almost identical ideas were tried out to distort heat as it scatters in space. In a two-dimensional cloak, most of the heat could be controlled to move about a covered region 300 micrometers across. In spite of the fact that heat isn't completely shut off, but only delayed from scattering in the cloaked region, Guenneau says that this concept has got huge potential in impeding the materials from heating up too fast.
With computers being developed on smaller scales, it’s difficult to assimilate fans or heat sinks to counter the heat, believes Nicholas Fang, a professor in Mechanical Engineering at MIT. This paper unfolds new possibilities to scatter away the heat laterally and uniformly through all directions, he added.
