Polarization and spectral properties of a photonic crystal with a ferrite-semiconductor metamaterial inclusion

In this paper the electromagnetic waves propagation in a photonic crystal with an embedded inclusion of subwavelength ferrite-semiconductor periodic structure to form the defect region are investigated. The system is placed into an external magnetic field applied along layers interfaces. The numerical and analytical results by transfer matrix method (TMM) show that, for the proposed PC with appropriate parameters the effective control of the polarization state of the reflected and transmitted electromagnetic wave (phase difference, polarization rotation angle and ellipticity) is possible by varying several system parameters: magnetic field, thicknesses of the layers, physical parameters of materials which form the PC and metamaterial. These properties may result in the design of improved PC devices, like polarizer´s, splitter´s, and so on.
