摘要
本文应用时域有限差分 (FDTD)方法研究电磁脉冲斜入射下无限长细导线的表面感应电流 ,并考虑了有耗地面的影响。该问题可以转换为二维问题来计算 ,从而大大节约计算资源。
The induced current of an infinite thin wire located above a lossy homogeneous medium due to an electromagnetic pulse (EMP) is computed by using the finite difference time domain (FDTD) method. The oblique incident case is simplified to a two dimensional problem. Results for various cases are demonstrated.
