Abstract

By utilizing Floquet driving protocols and interlacing them with a judicious reservoir emission engineering we achieve extreme non-reciprocal thermal radiation. We show that the latter is rooted in an interplay between a direct radiation process occurring due to temperature bias between two thermal baths and the modulation process which is responsible for pumped radiation heat. Our theoretical results are confirmed via time-domain simulations with RF circuits.
