Abstract

Electromagnetic wave propagation along the interface between a magnetoactive 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 (ωp, ωc), where ωp is the plasma frequency and ωc is the cyclotron frequency. The field topology is found, and the physical character of the waves is discussed.
