The spectrum of electromagnetic waves in a magnetized gaseous plasma layer. Part 1. Wave dispersion

Abstract

A numerical investigation of wave propagation in a magnetized plasma layer is performed. Four families of waves can propagate: plasma, cyclotron, anisotropic and waveguide modes. It is shown that the singular waves propagate at the crossing points of the waves with the complex zone boundary. The influence of the interface, the layer width and the magnetization of the plasma on the spectrum of the waves is analysed.
