inuence of externally applied elds and the internal elds generated by all
the other plasma particles. If the total number of particles is N, we have N non-
linear coupled differential equations of motion to solve simultaneously. A self-
consistent formulation must be used since the particle trajectories (elds) are
intrinsically coupled. The electromagnetic elds obey Maxwell’s equations:
