Study on attenuation characteristics of millimeter wave in plasma

为了研究毫米波与等离子体的相互作用,采用时域积分法对毫米波在等离子体中传输时的衰减特性进行了仿真,初步研究了毫米波在等离子体中传输时的衰减值与等离子体密度、碰撞频率及其工作频率之间的关系.通过理论结果和仿真结果的分析比较,验证了仿真可以为理论研究提供数据支撑的可行性.

In order to study the interaction between millimeter wave and plasma, by using time-domain integration method to simulate the attenuation characteristics of millimeter wave propagation in the plasma , this paper makes preliminary study on the relationships betwcen the attenuation value of millimeter waves propagation in the plasma, plasma density, the collision frequency and operation frequency. By comparing and analyzing the theoretical results with simulation results, the feasibility of the fact that simulation can be used to provide data support for the theoretical study is verified.
