该论文介绍了电磁场积分方程的无网格数值计算方法，传统的体积分数值计算都需要进行网格剖分，网格剖分的好坏直接影响着数值计算的速度和精度，很多精细结构很难用网格来模拟，无网格技术可以很好地解决此类问题！-This paper describes the meshless numerical method electromagnetic integral equations, numerical integration of traditional body calculations require meshing, meshing a direct impact on the speed and accuracy of numerical calculation, many very fine structure difficult to simulate with the grid, no grid can solve this problem!
