An implicit method for electromagnetic plasma simulation in two dimensions

A new method for modeling low-frequency plasma phenomena is presented. The method uses an implicit formulation of the Vlasov-Maxwell equations to relax restrictions on the time-step and mesh spacing so that larger values which correspond to the frequencies and wavelengths of interest can be used. As...

Summary:A new method for modeling low-frequency plasma phenomena is presented. The method uses an implicit formulation of the Vlasov-Maxwell equations to relax restrictions on the time-step and mesh spacing so that larger values which correspond to the frequencies and wavelengths of interest can be used. As a result, the range of length and time scales accessible to plasma simulation is increased by orders of magnitude. The algorithm, as embodied in a new code VENUS for electromagnetic plasmas in two dimensions, is described, its stability and accuracy analyzed through linear and nonlinear analysis, and its properties, including suppression of the finite grid instability, illustrated through its application to the Weibel instability.
