Abstract :
In the two-dimensional geo-electric model, the tipper response of magnetotelluric(MT) depends on the numerical simulation TE mode. Firstly, the boundary value problem and variational problem were shown, and the finite element method was used for element subdivision, interpolation, integration and general synthesis. Secondly, the electric field value of each node was obtained through solving the complex equation. Lastly, the partial derivatives along the horizontal and vertical electric field obtained using the difference method, and the tipper response of the two-dimensional MT can be calculated. By the numerical simulation of the two models, the tipper responses are obtained including real part, imaginary part and amplitude, and the results reflect the horizontal distribution of the body.
