| Abstract: | In this paper, the surface charge and current were used to represent the potential and the magnetic potential and a series of integral equations were obtained.A higher order form function was used to deal with discrete boundary integral equation, which greatly improved the accuracy of the solution.Finally, the numerical simulation particle scattering with different shapes and numbers was considered, the validity of algorithm was verified. |
