Analysis on polarization characteristics of electromagnetic propagation in anisotropic magnetized plasma media

The electromagnetic (EM) wave propagation through an anisotropic magnetized plasma layer is studied using the finite-difference time-domain (FDTD) method based on the Runge–Kutta exponential time differencing (RKETD) technique. When the propagation direction of the EM wave is perpendicular to the external magnetic direction, Voigt effect should be considered. The RKETD–FDTD formulations are derived in detail and are confirmed by computing the reflection and transmission coefficients for the ordinary polarized wave and extraordinary polarized wave through a magnetized plasma slab. Excellent agreement between the numerical results and the exact analytical solutions is demonstrated. The EM wave become partly longitudinal and partly transverse in magnetized plasma medium due to the Voigt effect are also proved.
