Abstract

The properties of electromagnetic waves propagating in magnetized plasma slabs and scattering from plasma coated spheres are investigated using the discontinuous Galerkin finite-element time-domain (DGFETD) method. The magnetized plasma is a kind of gyroelectric anisotropic dispersive medium. This anisotropy must be described by an electric permittivity tensor with both nonzero diagonal and off-diagonal elements. Instead of doing the convolution directly in the time domain, an auxiliary differential equations (ADE) method is employed to represent the constitutive relation. The algorithm is validated by studying the transmission characteristics via electron-composed plasma slabs and radar cross section (RCS) of plasma-coated spheres. All numerical results demonstrate very good agreements with exact solutions and comply with the plasma physics. © 2013 IEEE.
