Magnetotelluric Responses of an Anisotropic 1-D Earth with a Layer of Exponentially Varying Conductivity

The magnetotelluric (MT) sounding of a layered Earth model involving transitional layer has been widely studied, and MT responses the with dipping anisotropic conductivity have also treated. However, incorporating both anisotropy seldom considered. analytical solution such geoelectrical including three layers was derived in this study. middle exponentially varying depth, which covered by homogeneous underlaid half-space. electromagnetic (EM) fields were explicitly solved modified Bessel functions. surface impedance calculated recursively. dependence apparent resistivity phase as well EM on different parameters investigated detail. We believe that our provides useful complement to theory one-dimensional (1D) inversion interpretation based fixed conductivity.
