【摘要】 基于加权余量法,用自由空间的格林函数作为权函数,导出了边界元法(BEM)的详细方程。对无限远以及边界上的情况进行妥善设置,并采用高斯积分公式和刚体位移法对矩阵元素的计算进行优化。自行研究了不规则电磁场的计算程序,计算结果和理论值符合良好。更多还原

【Abstract】 Based on the weighted residual method, using Green’s function of free space as weighting function to get the detailed equation of the boundary element method. After that, properly handle the situation of infinite boundary, using Gaussian integral formula and rigid displacement to optimize the calculation. Develop the program of irregular electromagnetic field myself, and the numerical results are in good agreement with those theoretical values.更多还原
