在fdtd材料库中设置kerr系数的虚部请参考 https://support.lumerical.com/hc/en-us/articles/360034394734-Advanced-and-custom-optical-material-models-in-FDTD-and-MODE

设置材料的n、k系数,先输入这种色散材料,如果库了没有的话。在添加非线性材料时,选择这个材料作为基础材料即可。

比如选Si作为基础材料,那么应该这样设置:

你需要给出非线性模型中的参数.

老师您好,很感谢您的回答,也解决了我一部分疑问。但是关于kerr系数的虚部设置我无法在您给出的网页中找到方法,比如我需要设置三阶非线性系数时,在这里我只能填入实数,那么虚部该如何设置呢?
