Abstract: Dispersion properties of circularly polarized eigenwaves propagating in the “semiconductor-magnet” layered periodic structure along the axis of its periodicity and external magnetic field have been considered. The possibility of controlling the effective material parameters of the structure and the feasibility of negative refractive index for the wave with right (resonant) circular polarization has been shown. High magneto-optical activity of this gyrotropic structure has been ascertained, which leads to large Faraday rotation angles if the structure is in the state of “left-handed” medium.
