This paper is devoted to the investigation of the dispersion properties of slow electromagnetic surface waves on the harmonics of ion and electron cyclotron frequencies (SCW) in planar metal waveguide with plasma filling. Plasma layer is bounded at the planes x = 0, a by metal slabs. The authors consider nonordinary polarized waves, propagating across the external magnetic field {rvec B}{sub 0}. The problem is solved using Vlasov-Boltsman kinetic equation for the description of plasma particles and Maxwell`s equations set for the SCW field. They use the diffuse model of the particle interactions with plasma-metal boundaries. Analytical and numerical analyses show, that the SCW dispersion characteristics are slightly dependent upon thickness of plasma layer. This wave propagates only in one direction, which is determined by the direction of Larmor rotation of plasma particles near plasma-metal interface. The SCW skin depth approximately equal to their wavelength. It seems for us, that one directional propagation of the SCW makes it very important for different devices construction in plasma electronics.
