Finite-Difference Time-Domain Technique for Gyroelectric Material Structure Simulation Using Recursive Convolutions in Polarization

A gyrotropic material handling method is proposed. Our technique does not require modification of the finite-difference time-domain stepping algorithm, and the gyroelectric phenomenon can be treated as a variation of material polarization. The simulation of electromagnetic wave transmission through a test gyroelectric structure of a magnetized plasma layer is presented and compared with the analytical solution. An open source implementation is presented.
