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

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