Surface cyclotron waves in a nonuniform plasma filled metal waveguide with dielectrical coating

The problem concerning the dispersion properties of the slow extraordinary polarized electromagnetic surface waves on the harmonics of ion and electron cyclotron frequencies (SWCH) in magnetoactive plasma is studied. An external steady magnetic field is applied parallel to the plasma interfaces, rectangular with respect to the group velocity of the considered waves. The influences of the transverse plasma density nonuniformity, the plasma particle concentration, the external magnetic field value and the dielectric coating of the waveguide metal walls on the dispersion properties are considered. A theoretical investigation is carried out under the condition of weak plasma spatial dispersion using a kinetic plasma model. The obtained results can be used in branches of plasma electronics and plasma edge physics.
