Abstract : Modal methods are employed to represent the electromagnetic fields due to confined source distributions in an infinite, homogeneous, gyrotropic dielectric, with special emphasis on the case of a magnetoplasma. It is shown how the plane wave refractive index surfaces for the medium may be employed to impose the radiation condition, to locate stationary points in the integral representation, and to interpret the asymptotic field approximation in ray-optical terms. The field behavior in transition regions is emphasized. The results are then extended to plane stratified media, with the gyrotropic axis parallel to the direction of stratification. The discussion concludes with the treatment of simple diffraction problems wherein unidirectionally propagating surface waves may play a role. (Author)
