MT forward modeling of 3-D anisotropie electrical conductivity structures using the rayleigh-fourier method

We present an algorithm for modeling the magnetotelluric response of three-dimensional multilayered structures with irregular interfaces. In this formulation, based on a RayleighFourier technique, the effect of vertical anisotropy in the electrical conductivity has also been included. This method ha...
