导电圆柱在电磁脉冲照射下产生的表面感应电流

The Induced Current on a Conducting Cylinder Induced by an Electromagnetic Pulse

本文导出了当有一个 E—极化电磁脉冲平面波,向一无限长导电圆柱入射时,在柱体表面产生的瞬态感应电流波形的理论计算公式。作了相应的数值计算,讨论了计算精度,并与在电磁脉冲模拟器中对有限长柱体所作实验结果加以比较。

The pulse shapes of the current on an infinitely long conducting cylinder induced by an E-polarized incident electromagnetic pulse are calculated.The current density on the cylinder may be expressed by the sum of a few terms.The results are compa- red with the measured current pulse sequences on a finite cylinder in the parallel-plate EMP Simulator.
