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.

建议先用VarFDTD优化,然后再用3DFDTD设计,否则你现在扫描的范围可能离最佳结果很远。优化参数包括

光栅周期,占空比,耦合角度,光栅形状等。

网上例子都是经过反复仿真得到的较佳的结果。
