Abstract :
The transformation of time-harmonic plane electromagnetic wave (EMW) in a suddenly created cold and lossless magnetoplasma was considered. The static magnetic field was arbitrary oriented. The plasma was considered to be a two component (electron and ion mixture) when longitudinal and transverse propagation were considered. It was shown that for an arbitrary orientation of the static magnetic field in an electron plasma, the original linearly polarized EMW splits into eight wave modes with different orientations and energies and one nonpropagating wave mode. Some of the wave modes were strongly influenced by strength or by orientation of the external static magnetic held. When ions are included in analysis it was shown that the energy of low-frequency transverse wave modes exceeds that of the longitudinal modes and also that nonpropagating magnetic field mode disappears, which differs from the results where only electron plasma was considered. The energies of the wave modes formed in the pure electron plasma only slightly differ from that when ions are included into account. The dispersion relation and amplitude distribution of the different wave modes were presented by the use of suitable diagrams.
