摘　　要：等离子体参数的变化对在其中传播的电磁波有重要影响,文章采用周期性边界条件的二维PIC粒子模拟程序对电磁波在等离子中的传播过程进行了数值模拟,给出了电磁波在不同密度等离子体中传播的色散关系,得到了电磁波在等离子体中的传播特性。其结果,将作为进一步实现电磁波与等离子体中空间电荷波产生波-波相互作用过程模拟的基础。The change of plasma paper, the two-dimensional Particle parameter has direct effect on the electromagnetic wave in plasma. In this In Ceil （PIC） simulation program with periodic boundary condition is used to numerically simulate the diffusion of electromagnetic wave in plasma. The dispersion relation of electromagnetic wave in different-density plasma is given. The results in this paper would be taken as the basis for further simulations of the wave-wave interaction process between electromagnetic wave and space charge wave.
