Asymmetric Band Diagrams in Photonic Crystals with a Spontaneous Nonreciprocal Response

Filipa R. Prudêncio, Sérgio A. Matos, Carlos R. Paiva

We study the propagation of electromagnetic waves in layered photonic crystals formed by materials with a spontaneous nonreciprocal response, such as Tellegen (axion) media or topo…
