Maximal violation of Kirchhoff's law in planar heterostructures
Violating Kirchhoff's law is generally achieved using patterned nonreciprocal materials, where a guided or polaritonic mode that lies outside the light cone, often via gratings, is excited. Here, we describe how nonreciprocity manifests itself in pattern-free heterostructures. We demonstrate th...
