POLARITONS ALONG THE INTERFACE BETWEEN AN ANISOTROPIC SEMICONDUCTOR AND A METALLIC SCREEN

Surface polaritons along the interface between semiconductor magnetopl asma and a metallic screen have been investigated numerically. The pro pagation of surface waves in such a system is possible due to their Ra yleight character. It is shown that these electromagnetic waves are Ra leigh surface or Rayleigh generalized surface ones. The well known dis persion equation has been corrected and from the result of this it is proved that the dispersion curve in strongly magnetized plasma is fini te. In this case the wave is a ''virtual excitation'' surface plasmon. The partial waves interpretation and the field topography investigati on permit to receive a clear and distinct physical picture of the surf ace polaritons.
