电磁脉冲模拟器空间场分布的数值模拟
-
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。Abstract: The purpose of this paper is to determine numerically the transient spatial distribution of electric field in an electromagnetic pulse simulator excited by a time varying high power 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.
