Subscriber老师您好,mode expansion monitor的目的是为了方便提取波导模式中指定模式的透射率或透射率系数?
如果做空间光结构的仿真,设置平面波光源和field monitor,同样设置mode expansion monitor,但模式数设置为fundamental mode,这样提取的透过率是否和field monitor 提取的透射率一致?
(主要是因为利用lumopt进行伴随优化时,原代码都是关于波导类结构的优化,所以设置了mode expansion monitor,我想改成空间光结构的优化,只将模式数设置为fundamental mode是否合理?)

Ansys Employeefield monitor 提取的透射率是总透射率,含各个不同的激发模式。
mode expansion monitor的目的是为了提取波导中指定模式透射率或透射率系数。如果模式数设置为fundamental mode,那么模式透射率或透射率系数就是这个基模的结果。如果选择多个模式,不同模式均有自己的模式透射率或透射率系数。
只有你后面的问题,我不太清楚“空间光结构”是指什么,指结构光?先解决前面概念问题,再有问题请另外发帖。
