2DMT Contrast Research for Symmetrical Anisotropic and Isotropic Bodies

In this paper, by comparing the basic equations and variational problem of two-dimensional magneto telluric (2DMT) method for symmetric anisotropic with isotropic bodies show the difference between the two cases in TE (Transverse Electric) and TM (Transverse Magnetic) modes. This paper adopts rectangular element subdivision and bilinear interpolation. The comparison results show that in TM mode the measuring point above the abnormal body can more effectively reflect the anisotropy effect than the one which is far away from the abnormal body. In addition, the results demonstrate that in TM mode the anisotropy effect cannot be ignored, and then in TE mode it is not sensitive to the anisotropy.
