New 'Thermal' Approach to Invisibility Cloaking Hides Heat to Enhance Technology

In a new approach to invisibility cloaking, a team of French researchers has proposed isolating or cloaking objects from sources of heat -- essentially "thermal cloaking." This method, which the researchers describe in the Optical Society's (OSA) open-access journal Optics Express, taps into some of the same principles as optical cloaking and may lead to novel ways to control heat in electronics and, on an even larger scale, might someday prove useful for spacecraft and solar technologies.
