A quasistatic analytical approach is applied to the magnetotelluric responses of an idealized two-dimensional (2-D) horizontally nonhomogeneous model consisting of any number of segments with electrical anisotropic conductivity underlain by a perfect conductor basement. For this model, the magnetic field vector is everywhere parallel to the vertical contacts and to the Earth’s surface. The solution to the magnetotelluric responses of the model are derived, and detailed expressions for the electric and magnetic fields for a specialized case are presented. The resulting quasianalytical solution is then given for use in validation of numerical algorithms.
