"The underlying idea is to guide heat around the region which you'd like to protect from thermal flux," Guenneau told Discovery News.
A key finding in this research is that the team realized cloaking heat would not require exotic, manmade materials, known as metamaterials, typically used to cloak objects from other kinds of light waves or even sound waves. That's good news for this kind of cloaking because it can use standard materials already available.

Guenneau said the team didn't try to cloaking any human-sized objects from infrared light, though it's clear that the ability to shield them from infrared cameras would be of real interest to the military. Instead, their mathematical models focused micrometer-sized objects - the size range of most electronic components inside computer chips. Keeping these components cool is of big interest to the electronic industry, which spends millions of dollars just trying to keep Internet servers from overheating, not to mention individual laptops.
