你要的是什么结果？你知道光栅或者任何周期结构的响应与入射角有关，参见光栅方程。

你应该是只能每次仿真一个角度，再根据光源是否相干，将结果相干叠加（场量），或者非相干叠加（强度或者透射率反射率）。

如果是单波长，用BLoch边界条件： https://optics.ansys.com/hc/en-us/articles/360034382714-Bloch-boundary-conditions-in-FDTD-and-MODE

如果是宽光谱，靠有用BFAST：https://optics.ansys.com/hc/en-us/articles/360034902273-Broadband-Fixed-Angle-Source-Technique-BFAST
