摘要
When subjected to a constant magnetic field, both plasmas and ferrites exhibit anisotropic constitutive parameters. For electronic plasmas, the focus of this paper, the must be described by using a permittivity tensor in place of the usual scalar permittivity. Each member of this tensor is also very frequency dependent. This paper describes a finite-difference time-domain formulation which incorporates both anisotropy and frequency dispersion at the same time, enabling the wide-band transient analysis of magnetoactive plasma. Results are shown for the reflection and transmission through a magnetized plasma layer, with the direction of propagation parallel to the direction of the biasing field. A comparison to frequency-domain analytic results is included.
