Discrete modelling of plasma equations with ion motion using technique of wave digital filters

This paper shows how to solve a system of plasma equations consisting of Euler´s and Maxwell´s equation systems by using technique of wave digital filters. Since, in plasmas, the electromagnetic effect superposed in addition to the effect of thermal motion in the fluid, both Kirchhoff circuits derived from the equation systems have to be connected each other, which are transformed into well-known WDF algorithm, leading to a solution of plasma equations
