摘要
利用时域积分方程对电磁脉冲模拟器在瞬态电磁场激励下的空间场分布进行了数值模拟，给出了模拟器内部场的建立情况及分布规律。结果表明：过渡段与工作段连结处的电流不连续性将引起场波形的畸变；电流的前向辐射是场的主要贡献者，水平电场分量的幅值非常小，电磁脉冲模拟器场的传播具有准横电磁波的特性。
The purpose of this paper is to determine numerically the transient spatial distribution of electricfield in an electromagnetic pulse simulator excited by a timevarying highpower pulse source using an integral equation of the time domain. Some conclusions are drown from the data that a period of time are required for the electromagnetic pulse field to be established in the electromagnetic pulse simulator; the discontinuance of the current in the joint segment between conical region and working region is the main reason of the deformation of the field waveforms; The forward radiation of the current is the main reason for the field to be established and the afterward radiation contributes quite a little for the field to be established; The amplitude of horizontal electricfield is quite weaker than that of vertical electricfield.
