“…The central part of the grid has small elements and dense nodes, and the edge elements are large and sparse. The cells are gradually enlarged from the center to the edge to ensure that the grid has sufficient size, and the complex parts of the geoelectrical section are located in the dense center of the grid to meet the conditions of uniform electrical properties in the cell and linear changes of the electromagnetic field potential function [10]. When solving the finite element method corresponding to the Helmholtz equation, the solution of the continuous field function is converted into the solution of the discrete function value at the node by using the cross-symmetric grid.…”

Among the geophysical exploration methods, conventional magnetotelluric methods have extensive and in-depth applications in many fields such as deep crustal structure and petroleum exploration. In this paper, by using the Cole-Cole model to introduce the complex resistivity into the Maxwell equation, the feasibility of extracting the four parameters of the Cole-Cole model from the observation data is explored, and finally the programming realizes the magnetotelluric two-dimensional tilter positive performance research. The staggered grid finite difference method is used for forward modeling, the conductivity in Maxwell equation is replaced with complex conductivity through Cole-Cole model, and Maxwell equation is discretized based on staggered sampling grid division and combined with boundary conditions to obtain the electric field value satisfied Linear equations. This paper analyzes the influence of the parameters of the Cole-Cole model on the polarizer through the forward simulation of two polarizers in a uniform halfspace. The forward modeling results of the model show that the existence of the IP effect will increase the apparent resistivity value, and different IP parameters have different effects on the apparent resistivity. Among them, the polarizability has the greatest influence on the apparent resistivity; the greater the polarizability is , the greater the apparent resistivity.
