Sažetak
The nonlinear resonant interactions among two circularly-polarised waves and a Langmuir wave in a cold plasma subjected to a magnetic field directed parallel to the direction of propagation of the three waves are considered. The method of multiple time-scales is used. It is found that if two circularly-polarised waves with opposite polarisations and large amplitudes interact, then a Langmuir wave can be excited, and further that it is possible for a large amplitude Langmuir wave to decay into two circularly-polarised waves with the same polarisation. Next, the nonlinear resonant interactions among three extraordinary waves in a warm-plasma subjected to a magnetic field directed perpendicular to the direction of propagation of the three waves is considered. The method of coupled-modes is used.
