[已解决]请牛人指教一下，三维程序中均匀平面波入射时连接边界这样加入有问题吗？

里面的计算过程根据葛老师编的书上公式！（前4个式子计算E0，后面两个坐标转换，不知道这样对不对）请教牛人指导，磁场也按同样方法加入！ 3t<XbHF9

从运行结果来看，不正确，不知道是不是这一步有问题？做过这样程序的一定指教一下小弟！

自己顶一下！ |:!0`p{R  
书中的计算r'的公式是不是错了？其中中间的一项中cos（theta）是不是要改为sin（theta）？又知道的嘛？自己推算的时候感觉书上的错了，有不敢冒昧！望牛人指点！

中间一项本来就是sin（theta）

  JpuW !I  
貌似这里也不对，left_x(i,1,k)好像在第二步的时候值已经改变了。不应该用这个迭代吧！

谢了，今天一天确实找了很多毛病，不过你提的这个错误，还没发现呢！茅塞顿开了！不知该说啥了，谢谢您了！o(∩_∩)o...明天再调调试试！

明天就回家了，再来顶顶！

有空看看。

我曾经推导过，我想看看你的程序吧
