The numerical method of integral equation in the electric field based on Gaussian numerical integral method

This article discusses an iterative method for the numerical solution of the integral equation in the electric field. This algorithm is based on the Gauss-Seidel iterative method and the Gaussian numerical integral method. Specifically, in the framework of the method of moments, it used Gaussian numerical integral method to obtain linear equations of the discrete electric field integral equation for the integral of the integral equation in electric field. The coefficients of the linear equations are known functions whose showing constitute the linear equations. After that, it adopts the Gauss-Seidel iterative method to solve the system of linear equations.
