对于一个周期结构(如光栅),采用倾斜的平面波入射,请问FDTD的边界条件能否用对称(symmetric BCs)和反对称(anti-symmetric BCs)?能否得到与Bloch边界条件一致的结果?

没有入射角的那个面还可以用对称(symmetric BCs)和反对称(anti-symmetric BCs),有入射角的面必须用Bloch,如果是单波长的话。如果用BFAST,它有自带的边界条件,只是没有入射角的一面仍然可以用对称(symmetric BCs)和反对称(anti-symmetric BCs)。
只有有入射角的面才有特殊要求。
如果有入射角的面用对称(symmetric BCs)和反对称(anti-symmetric BCs),那就错了!
