Nonreciprocal Thermal Photonics for Energy Conversion and Radiative Heat Transfer

Nonreciprocal thermal photonics is an emerging topic in thermal radiation control. Recent advances in using this approach for energy harvesting, thermal management, and even communication have stimulated substantial interest in the subject. The authors review recent developments, challenges, and opportunities in the unidirectional transfer of heat energy via light, to provide a snapshot of the current status of the field, and to advance future research in it.
