Thermal radiation, which originates from random fluctuations in materials, is traditionally considered an incoherent signal. Most conventional thermal emitters show weak to zero circular polarization ...

Researchers have broken a centuries-old law of physics, putting us on a path towards making better energy-harvesting devices, such as solar cells. Atoms at temperatures beyond absolute zero may be a ...

A thermal metasurface is made of a single layer of nanostructured silicon (gray) on top of glass (blue) and a metal mirror (gold). The nanostructured surface is specifically tailored so that it ...

All objects that have temperature release thermal radiation, which is electromagnetic radiation. The solar radiation spectrum is the most representative type of thermal radiation since it enters the ...
