Abstract
ABSTRACT Slow surface wave propagation along the boundary of two diagonally anisotropic dielectric media (or bi-axial crystal) in a metallic cylindrical waveguide with an excitation by a magnetic ring source is studied. The results of this general problem have been applied to study the wave propagation in plasmas in the presence of a zero or infinite uniform d.c. magnetic field in the axial direction. Numerical results have been obtained for these special cases. Although attention is directed towards the study of the slow surfaee wave propagation, the general expressions for fields and dispersion relation are valid for any possible mode of propagation in the structure. It is shown that for slow waves the axial component of one of the dielectric tensors must be negative.
