摘要

为研究发光等离子体对高功率微波的防护性能，建立了一维条件下等离子体与高功率微波相互作用的物理模型，并采用数值仿真得到了不同条件下的微波透射效果，分析了发光等离子体对高功率微波的防护性能。随后，实验研究了双层柱状等离子体阵列对6 GHz高功率微波脉冲的透射效果，实验结果与仿真结果相符，说明高功率微波的入射使等离子体产生了非线性效应。实验结果还表明，TE极化时的防护效果要优于TM极化时的防护效果；等离子体击穿场强阈值随电场作用空间的增大而减小；TE极化时等离子体对高功率微波脉冲的屏蔽效能最高可达13 dB，且随入射功率的增大而进一步增大。

Abstract

In order to investigate the protection performance of light emitting plasma to high-power microwave (HPM)

a one-dimensional physical model of their interaction was built theoretically. The microwave transmission effect under different conditions was obtained by numerical simulation and the protection performance of light emit-ting plasma on HPM was analyzed. Then

the experiment about transmission effect of double columnar plasma arrays on 6 GHz HPM pulse was conducted. The effectiveness and veracity of the model were verified by comparing the results of theoretical calculation and experiment

and a nonlinear effect can be produced by the HPM plasma incidence. The results also show that TE polarization is better than TM polarization in protection. The plasma breakdown threshold decreases with the increase of the electric field space. The maximum attenua-tion of TE polarization can be up to 13 dB and increase further along with the input power.
