Circular polarized thermal radiation

Caption

Thermal Image of Wabash River (left), near Purdue University's campus. Most conventional objects show weak to zero circular polarization in the emitted heat signal. By using metasurfaces (right) made up of arrays of F-shaped nanostructures with various symmetries, researchers are able to generate circular polarized thermal radiation in a controlled and efficient manner.
