使用有限元方法计算了介质球存在下的三维电磁场分布情况，入射波使用高斯形式。-finite element method for 3D electromagnetic field distribution

该程序通过读取的文本中的三维坐标点信息，通过最小二乘和神经网络来进行拟合，得到球的圆心和半径。-The program information through the text to be read in the three-dimensional coordinate point, by the least squares and neural networks to be fitted to obtain the ball center and the radius.

基于matlab的三维边界元法。可以计算金属球，金属棒，金属圆环等结构的远场光散射和场分布。-Matlab-based three-dimensional boundary element method. You can calculate the metal balls, metal rods, metal ring structures such as the far-field light scattering and field distribution.
