ELECTRON SURFACE CYCLOTRON WAVES IN THE METALLIC WAVE-GUIDE STRUCTURES WITH 2-COMPONENT FILLING

The dispersion properties of the slow electromagnetic surface waves pr opagating across external magnetic field in planar metallic waveguides with plasma and dielectric filling on the harmonics of the electron c yclotron frequency are studied in this paper. The external steady magn etic field is supposed to be directed perpendicularly to the waveguide wall. Dielectric layer separates semibounded plasma from the metallic wall. The analytical research is carried out using the kinetic descri ption for plasma particles: the mirror reflection model for the intera ction between particles and plasma boundary. Skin depth of the surface cyclotron waves (SCW) is much greater than electron Larmor radius. Ef fect of the following parameters of the waveguide structures: dielectr ic constant and thickness of the dielectric layer, plasma density valu e and number of tile cyclotron harmonics, on the SCW dispersion is exa mined both analytically and numerically.
