摘　　要：在电磁系统中,电磁场的场域计算对于完成电磁系统的有效设计是极为重要。为了求解电磁场,一般采用有限差分法,而有限差分法包括简单迭代法和超松弛法。本文对其有限差分法中的简单迭代法和超松弛法进行了理论分析。通过两个简单的问题模型,采用MATLAB软件进行仿真计算,以图表方式直观的展现计算结果,并对比了两种方法在不同网格下的特性。In the electromagnetic system,the field calculation of the electromagnetic field is extremely important for the effective design of the electromagnetic system.Generally,the finite difference method is used to solve the electromagnetic field,which includes a simple iterative method and an over-relaxation method.In this paper,the simple iterative method and the super-relaxation method in the finite difference method are theoretically analyzed.Through two simple problem models,the simulation calculations were carried out using MATLAB software,and the calculation results were visually displayed in a graphical manner,and compare the characteristics of the two methods under different grids.
