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: the y are superpositions of two partial waves. It is concluded that electr omagnetic waves propagate only at frequencies lower than min (omega(p) , omega(c)), where omega(p) is the plasma frequency and omega(c) is th e cyclotron frequency. The field topology is found, and the physical c haracter of the waves is discussed.
