摘要

本文建立了具有全张量介质和电导率各向异性的多层地层中电偶极源和磁偶极源辐射的电磁场。通过在谱域中重新表述麦克斯韦方程组，在空间域中利用傅里叶变换求解电场和磁场，可以获得偶极子源的电磁响应。多层地层的总场由上下两层的直波场和反射波场组成。推导了广义反射矩阵和透射矩阵来表示任意层中的波场。数值计算结果与有限元计算结果吻合较好。

Electromagnetic Fields of Dipole Sources in Multilayered Arbitrary Anisotropic Formation

The electromagnetic fields radiated by electric and magnetic dipole sources in multilayered formation with full-tensor dielectric and conductivity anisotropy are formulated in this paper. By reformulating the Maxwell’s equations in the spectral domain and solving the electric and magnetic fields in the spatial domain using the Fourier transform, the electromagnetic responses from dipole sources can be acquired. The total field in multilayered formation consists of two parts: direct wave field and reflected wave fields from bottom and top layers. Generalized reflection and transmission matrices are derived to express the wave fields in arbitrary layers. The numerical results show good agreement with the finite element results.
