Abstract :
A novel general finite element solver for gyroelectric structures is presented. The solver is validated and compared with known gyrotropic waveguide solutions. Slab loaded semiconductor waveguides are investigated for nonreciprocity and differential phase shift is calculated. The proposed structures can potentially be exploited as nonreciprocal phase shift and control components for terahertz frequencies.
