A formal time-domain approach to cold magnetised plasmas
Abstract
Representations of the electromagnetic and the average velocity field for a cold magnetized plasma are derived in terms of scalar potential functions. These Hertz potentials are solutions of a coupled system of integrodifferential equations of second order. Different from other approaches, the analysis is carried out in the time domain and is, therefore, especially suited for the investigation of transient wave phenomena. Furthermore, the dielectric tensor operator of the plasma is derived. After solving the system of integrodifferential equations for a special limiting case, the applicability of the method presented is demonstrated and generalizations are discussed.
