In this work we study the response of a wire array embedded in a material with gyrotropic response. Using effective medium theory and full-wave simulations, we characterize the scattering of electromagnetic waves by the metamaterial. We show that the metamaterial can be operated in a regime where the reflectivity can be significantly different for angles of incidence linked by parity, so that for “positive” angles the waves are strongly absorbed and for “negative” angles the waves are mostly reflected.
