摘要
对介质体电磁散射问题采用电场积分方程建立了多个埋地均匀介质体的数值模型。对积分方程中并矢格林函数各分量所含的索末菲积分,应用离散复镜像理论化为闭合形式,简化了计算。本文针对双孔电磁波法情况,及单孔发射地面接收仅由散射体产生的垂直地表面的磁场,作了理论计算。所得结果对分析解释浅层实测数据有参考价值。
The scattering problem of dielectric body is formulated in terms of the electricfield integral equation.A numerical model for dielectric bodies with homogeneity buried inearth is established.For Sommerfeld integrals cantained in tensor Green's function,it is simpleto use discrete complex image theory to obtain close forms.This paper is aim at the case ofdouble hole electromagnetic wave method,and single hole for transmiting and the magneticfield perperdicular to the surface is received above the ground,which is yielded only by thescatterer.The results have referential value for analysing and tanslating the data measured inshallow stratum.
