Rigorous charge conservation for local electromagnetic field solvers

摘要: Abstract In this paper we present a rigorous method for finding the electric field in two-and-one-half and three dimensional electromagnetic plasma simulations without resorting to computationally expensive transforms. A finite grid interpretation of divergence equation ∇· J = -ϖρ/ϖt is offered which allows current density thus new local magnetic strengths be determined directly from knowledge charge motion.
