| 摘 要： | 利用电磁场张量法计算了平行板电磁脉冲模拟器内的电磁场并推导了其时域解析表达式。按照模拟器的平行板段和前后三角板的结构将平板近似为线网格。场的幅值由各线段元的不同滞后时间叠加来确定，其方向由线段元和场点的单位矢量经简单矢量运算来确定。计算结果表明：平行板段内的场具有横电磁分布特性，而靠近三角板处由于各线段元的非对称性贡献将使场出现其它分量。通过对模拟器的电场测量值与理论计算值相比较可知，两者大致相同。

| Abstract: | The electromagnetic field tensor method is used to calculate the electromagnetic fields inside a parallel-plate simulator and analytical expressions for the field distributions are derived in time domain. The solid metal plates are approximated as wire meshes according to the simulator structures, which are composed of the middle flat plates, the front and back triangular plates. The amplitudes of the electromagnetic field can be determined by the superposition of the different retarded time currents in the wire segments, and the direction can be determined by the simple unit vector operations of the wire segments and field point position. Calculated results show that the fields between the middle flat plates have the transverse electromagnetic distribution properties, and the field compon |
