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.

谢谢孙老师!我需要仿真的情况是会聚球面波通过一个厚3mm的石英基底,然后在基底另一表面,周期为微米级的光栅处衍射。目前来看,只能通过几何光学或者标量衍射方法计算光通过石英基底到达光栅附近的电场分布,然后将其作为input source输入到FDTD Solutions中。只是我比较担心这种方式不如矢量方法精确,会有较大的系统误差
