谢谢老师的回复，现在我还是有两个问题有点疑惑：
1.在我的实验中，光栅尺寸是1毫米*1毫米的，但中间区域的复合光栅尺寸为100微米*100微米，我更关注中间区域复合光栅的光场变化。所以我更想关注这部分的远场的电场模分布
2.下面是我的不规则复合光栅的示意图，但对于这种不规则的复合光栅的衍射级次和衍射角可以去计算吗？
We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.
