Microwave propagation in ferromagnetic semiconductors

Ferromagnetic semiconductors may exhibit gyroelectric and gyromagnetic behavior at the same time. In order to treat the Maxwell equations and the propagation in such semiconductors, the description of the two phenomena are unified in a general framework, concerning gyroelectromagnetic media. This allows one to describe the modes in waveguides with a gyroelectromagnetic core, so the high azimuthal index mode behavior may be predicted in ferromagnetic semiconductors, focusing on microwave frequency domain towards technological applications.
