摘要: Abstract An accurate, direct method for the simulation of magnetized, multi-dimensional plasmas is developed. A time decentered particle push combined with implicit plasma to include finite sized effects in an absolutely stable (under conditions which field corrector converges) algorithm. Second-order temporal accuracy attained when decentering parameter may be chosen smaller than normalized frequency interest. simple iteration (renormalized Poisson equation) used solve equation. Details two-dimensional, electrostatic, constant magnetic field, periodic case are given. Numerical results ion-acoustic fluctuations and unstable gravitational interchange confirm efficacy applied lowfrequency phenomena.
