摘　　要：对在频率为10 MHz-1 GHz的平面电磁干扰波照射下的窄缝腔体进行仿真研究,取箱体中心点为观察点,改变电磁波的照射方向以及极化方向,对比分析其耦合特性.实验结果表明:对于矩形孔缝,当极化方向垂直于窄缝长边时,发生共振效应,在共振频率附近一定带宽内耦合效应最大,并在共振频率处存在着场增强效应.This paper studies the simulation characteristics of cavity whit slot which is irradiated by plane wave with a frequency of 10 MHz-1GHz.taking the center of the cavity as observation point, Change the polarization direction and irradiation direction of the electromagnetic wave,Comparison and analysis of coupling characteristics.The results show that：the resonant effect will take place if the direction of the incident electric field is perpendicular to the long side of the rectangular slot.There is a strong coupling band near the resonant frequency,around which the enhancement effect can take place.
