Nonlinear resonant absorption and wave breaking (Vlasov simulation of resonance excited plasma waves)
Abstract
The resonant excitation, damping, and breaking of nonlinear Langmuir waves in inhomogeneous plasma, were examined in the condensator model of the resonant absorption. The Vlasov equation for the condensator model was resolved numerically. Fast Fourier transforms were used to solve the equation for the acceleration and the vectorization of the solution algorithm, so that computation time prolongation could be kept relatively small compared to particle simulation. Wave breaking in warm plasma was defined as a loss of periodicity. The dynamics were examined at different locations, using time series of electron density, and of the electric field.
