UWB电磁脉冲圆孔耦合计算及试验研究

摘要

Coupling electric field of UWB EMP through different diameter circle hole were caculated using microsoft CST. UWB radiation experiment was make on using metal cavity which same size as caculation. The electirc filed attenuation coffficient of CST caculation and radiation source experiment are consistent. The method of caculation and experiment are correct.%采用电磁场数值计算软件CST计算了前沿为400 ps的UWB电磁脉冲辐射场通过不同直径的圆形孔耦合到金属屏蔽腔体内的电场,对相同尺寸的带圆孔的金属屏蔽腔体在UWB辐射模拟源上进行了验证试验.通过理论计算和试验测试得到的电场衰减系数符合较好,证明采用的UWB电磁脉冲圆孔耦合计算及试验的方法是可行、正确的.
