Sammanfattning

In this paper transient electromagnetic wave propagation in a stratified, anisotropic,

dispersive medium is considered. Specifically, the direct scattering

problem is addressed. The dispersive, anisotropic medium is modeled by constitutive

relations (a 3 × 3 matrix-valued susceptibility operator)con taining

time convolution integrals. In the general case, nine different susceptibility

kernels characterize the medium. An incident plane wave impinges obliquely

on a finite slab consisting of a stratified anisotropic medium. The scattered

fields are obtained as time convolutions of the incident field with the scattering

kernels. The scattering (reflection and transmission)k ernels are uniquely

determined by the slab and are independent of the incident field. The scattering

problem is solved by a wave splitting technique. Two different methods

to determine the scattering kernels are presented; an imbedding and a Green

functions approach. Explicit analytic expressions of the wave front are given

for a special class of media. Some numerical examples illustrate the analysis.
