Abstract

The dispersion relation of azimuthal electromagnetic surface waves on a magnetized annular plasma surrounded by a metallic cylindrical coaxial anisotropic dielectric lined waveguide is obtained. The thickness of the dielectric and its location in the waveguide are studied with respect to their effects on the number of spectra observed. The graphs of frequency spectra against the ratio of radii of the annular plasma and eta=omega(pe)/Omega(e) are plotted. Finally, surface E-modes for coaxial anisotroplic and isotropic dielectrics have been investigated.
