【摘要】 本文介绍了1 2/2维相对论性、电磁模等离子体粒子模拟的方法和原理。系统地以计算机模拟了由电子气体组成的等离子体中的各种电磁波。在无外加静磁场、加外横磁场、加外纵向磁场等不同情况下,分别得到静电波、电磁波、寻常波、非寻常波、ω=nω_c的磁回旋共振、左旋波、右旋波等。其色散关系、截止频率、共振频率、极限相速度均与理论结果一致。更多还原

【Abstract】 The basic method and principle ofan 122 D particle simulation for a clativistic plasma of electromagnetic mode are introduced Various kinds of electromagnetic waves inaplasma which is composed of electron gas are simulated systematically by computer. In adifferent cases,such as plasmas without external magnetic field, with transverse or longitudinal magnetic field, the electrostatic wave, electromagnetic, ordinary and extraordinay waves, cyclotron resonance with ω=nωc, left and right circularly polarized waves are obtained. Their dispersion relations, cutoff frequencies and limit phase velocities are all in reasonable agreement with related theories.更多还原
