SURFACE-WAVES ON THE HARMONICS OF THE ELECTRON-CYCLOTRON FREQUENCY PROPAGATING ALONG A PLASMA-METAL INTERFACE

Dispersion properties of slow electromagnetic surface waves propagatin g on the harmonics of the electron cyclotron frequency across the exte rnal steady magnetic field are studied in the case when the magnetic f ield is parallel to the plasma-metal interface. Theoretical investigat ion of these surface modes is carried out using the kinetic descriptio n under the condition of weak plasma spatial dispersion, when the radi i of the charged plasma particles' Larmor rotation are much less than the spatial scale of the considered wave perturbation. The effect of t he plasma density transverse inhomogeneity, of plasma particles' conce ntration and of the external magnetic field value on the dispersion pr operties of the surface waves on electron cyclotron harmonics (SWCH) i s researched.
