摘要

建立了时域磁场积分方程(TD-MFIE)，并应用于研究垂直极化电磁脉冲在不规则地面上的传播机理。假定大气是均匀的，地面的导电性足够小，因此可以认为这样的地面是垂直极化的完美磁性导体。此外，假设地形轮廓电平滑，从而忽略后向散射，并采用正演方案来获得等效问题的表面磁流，同时采用随时行进(MOIT)技术来考虑时变特性。

A TD-MFIE for a vertically-polarized pulse propagation over irregular terrains

A time domain magnetic field integral equation (TD-MFIE) is developed and applied in the study of the propagation mechanisms of a vertically polarized electromagnetic pulse over an irregular ground. The atmosphere is assumed homogeneous and the conductivity of ground sufficiently small so to consider such ground a perfect magnetic conductor (PMC) for a vertical polarization. Furthermore, the terrain profile is assumed electrically smooth, such that back scattering is neglected and a forward scheme applied to obtain the surface magnetic currents of the equivalent problem, together with a marching-on-in-time (MOIT) technique to account for the time-varying characteristics.
