SURFACE CYCLOTRON WAVES IN A NONUNIFORM PLASMA-FILLED METAL WAVE-GUIDE WITH DIELECTRICAL COATING

The problem concerning the dispersion properties of the slow extraordi nary polarized electromagnetic surface waves on the harmonics of ion a nd electron cyclotron frequencies (SWCH) in magnetoactive plasma is st udied An external steady magnetic held is applied parallel to the plas ma interfaces, rectangular with respect to the group velocity of the c onsidered waves. The influences of the transverse plasma density nonun iformity, the plasma particle concentration, the external magnetic fie ld value and the dielectric coating of the waveguide metal walls on th e dispersion properties are considered. A theoretical investigation is carried out under the condition of weak plasma spatial dispersion usi ng a kinetic plasma model The obtained results can be used in branches of plasma electronics and plasma edge physics.
