摘要
用数值方法研究了超宽带电磁脉冲与地雷耦合问题。验证了截断有耗边界的完全匹配层方法,给出了超宽带信号经天线发射后在不同距离处的辐射场。通过数值模拟,给出了不同作用距离和作用角条件下地雷体内的耦合电磁场。
This paper numerically studies the coupling of the ultrawide band electromagnetic pulse into mines. Some typical coupling results are presented for different incident angles and distances from the antenna to the mine. In order to investigate the coupling problem, this paper studies the perfectly marched layer used to truncate the lossy boundary, and provides the distributions of the electric field radiated from the TEM horn antenna fed by the UWB signal.
