Our recent work on ‘Observation of nonvanishing optical helicity in thermal radiation from symmetry-broken metasurfaces’ has been published in Science Advances. We uncover a new method for generating spinning thermal radiation in a controlled & efficient manner using metasurfaces. 

Spinning thermal radiation is extremely rare in nature and is only found in some condensed stars. Our work provides a new way to generate this type of radiation, which has the potential to be used in a variety of applications such as thermal imaging and communication.
