Dispersion relation of azimuthal electromagnetic surface waves on a magnetized plasma column in a dielectric lined slow-wave waveguide

The dispersion relation of azimuthal electromagnetic surface waves on a magnetized plasma column surrounded by a metallic cylindrical dielectric lined slow-wave waveguide is obtained. The permissible frequency region for these waves in E- and B-mode is presented. Furthermore, the graphs of frequency spectra and radial dependence of fields on the external magnetic field strength, geometric dimensions of the waveguide, radius of plasma column and thickness of dielectric are investigated.
