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 attenuation of TE polarization can be up to 13 dB and increase further along with the input power.
