• In fluid theory, a system of plasma equations consists of a system of Maxwell's equations and that of Euler's equations. Maxwell's equation system is linear, while Euler's one is nonlinear. Therefore, both equation systems cannot be treated together in general. However, introducing power waves and the technique of wave digital filters (WDF), we can unitedly treat them to get a numerical solution in simulation. Moreover, this method is suitable for the time-dependent phenomena, since spatial and physical variables are calculated every sampling time. In this paper, as an example of numerical simulations, wave propagation phenomena in and around magnetized plasma are treated. As a result, scattering processes are simulated visually.
