RAYLEIGH SURFACE-WAVES ALONG THE BOUNDARY BETWEEN A PLASMA AND A METALLIC SCREEN

Electromagnetic wave propagation along the interface between a magneto-active plasma and a metallic screen is investigated analytically and numerically. It is shown that the waves have a Rayleigh character: they are superpositions of two partial waves. It is concluded that electromagnetic waves propagate only at frequencies lower than min (omega(p), omega(c)), where omega(p) is the plasma frequency and omega(c) is the cyclotron frequency. The field topology is found, and the physical character of the waves is discussed.
