Nonsymmetrical Electromagnetic Waves in Partially Plasma — Filled Waveguide

Abstract

The dispersion of nonsymmetrical electromagnetic waves in waveguide, partially filled with plasma, is studied numerically and experimentally. An external d.c. coaxial magnetic field is applied to the waveguide. The dispersion equation of these waves is obtained, and it is solved numerically for the experimental conditions. Results are obtained, which show coupling of the waveguide HEI,-modes with the family of the high-frequency plasma HEl,-modes. The numerical dispersion curves are experimentally examined, and the influence of the magnetic field and the plasma density is studied.
