Tunable Angular Spatial Filter Based on 1D Magnetophotonic Crystal

Abstract

One dimensional magnetophotonic crystal with gyrotropic plasma layers is considered. Theoretical investigation is performed within the framework of Floquet theory for 1D periodical structures. Dispersion equation, transmission coefficient and reflection one are obtained in explicit form. Scattering of the point source field on the bounded magnetophotonic crystal is investigated for TE waves. Field spatial distributions for different signs of plasma-like medium effective permittivity are calculated. Possibility of angular spatial filtering control is shown both inside magnetophotonic crystal and outside one.
