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.

仿真结果分析参见：

Ansys Insight: 周期结构结果：透射反射率、散射、远场、角分布、近距场分布、位相提取等 综合帖

Ansys Insight: 非周期结构散射的远场分析：散射截面、远场分布、斜入射 综合帖

偶极子对周期结构是相干的，不同位置不同偏振不同偶极子个数结果可能完全不同。你可以找一些参考文献看看。
