Abstract

The problem of a unipolar electromagnetic pulse being diffracted by an ideally conducting cylinder is considered using a computational experiment. It is shown that the scattered field is bipolar for the chosen polarization, with which the magnetic component of the field is parallel to the cylinder axis. The shape of its temporal profile depends on the ratio of the cylinder’s radius and the spatial length of the incident pulse.

极导体上的TM极化单极脉冲的非平稳衍射

摘要

使用计算实验来考虑单极性电磁脉冲被理想导电圆柱体衍射的问题。结果表明，对于选定的极化，散射场是双极性的，磁场的磁场分量平行于圆柱轴。其时间轮廓的形状取决于圆柱半径与入射脉冲的空间长度之比。
