从电张量格林函数的物理意义出发 ,在频率域和时间域研究了均匀导电半空间中的电张量格林函数 ,并基于 Fredholm方程分析了三维电磁散射的数值模拟方法。作者还根据实际情况 ,首次模拟出三维瞬变电磁激电异常的相位剖面图 。

According to physical sense of the tensor Green's function, the three dimensional tensor Green's functions in a homogeneous conductive half space both for time domain and for frequency domain are studied respectively. The method of numerical simulation about the three dimensional transient electromagnetic scatter is analyzed on the base of the Fredholm equation. A phase profile of three dimensional electromagnetic induced polarization is firstly modeled. The results are similar to that of the direct current condition and consistent to the practical data.
