A solver based on pseudo-spectral analytical time-domain method for the two-fluid plasma model

Abstract A number of physical processes in laser-plasma interaction can be described with the two-fluid plasma model. We report on a solver for the three-dimensional two-fluid plasma model equations. This solver is particularly suited for simulating the interaction between short laser pulses with pl...
