Abstract
Periodic layered structures with bi-isotropic media are studied with the aim to unveil nonreciprocal effects in the photonic band structures. It is shown that photonic crystals with both chiral and Tellegen materials can exhibit asymmetric band diagrams. A symmetry transformation that protects the spectral-symmetry of Tellegen photonic crystals is identified.
