Drifting Electrons: Nonreciprocal Plasmonics and Thermal Photonics
Drifting Electrons: Nonreciprocal Plasmonics and Thermal Photonics
Light propagates symmetrically in opposite directions in most natural and artificial materials. This fact, a consequence of the Lorentz reciprocity principle, has tremendous implications for science and technology across the electromagnetic spectrum. Here, we investigate an emerging approach to break reciprocity that does not rely on magneto-optical effects or spacetime …
