Nonlinear Behaviour of Lower Hybrid Waves near the Linear Mode-Conversion Point
Abstract
The nonlinear behaviour of the two-dimensional steady-state propagation of the lower hybrid wave near the linear mode-conversion point is investigated in the presence of the density depression due to the ponderomotive force. It is shown that an equation which governs the wave packet near the conversion point can be reduced to the nonlinear Schrödinger equation with a Iinearly increasing potential. Numerical analysis of the model equation visualizes the behaviour of the wave packet in the linear and the nonlinear regimes.
