请参考这个例子 https://optics.ansys.com/hc/en-us/articles/360042799933-Bent-waveguide-analysis
此时用dB/cm形式是否合适?dB/90°的形式可能更合适,但是是否考虑两边的直波导损耗呢?
如果仅考虑90度弯曲,请使用FDE,计算损耗可能更准确一些。

你好,请问你解决了FDTD如何计算90度弯曲波导损耗的问题了吗?光源source中的bent waveguide下的bend radius数值是如何计算的呢?亦或者是不需要设置bent waveguide,那么应该如何获得这种模式的传播损耗呢?

请参考前面链接,如果波导不一样的话。
如果就是普通的90度弯曲,请使用FDE:https://optics.ansys.com/hc/en-us/articles/360034917253-Solving-bent-waveguides-in-FDE-and-FEEM
将Neff换算为角量,再根据定义用90度乘其虚部。请花点时间考虑此方法。
