FDTD时变超表面仿真求助

      我想尝试对这篇关于时变介质的文献进行仿真复现,文章中说他是用lumerical FDTD进行仿真的,但限于水平,利用flexible material plugin中的stepindex插件,我不知道如何建模和仿真,抑或是使用FDTD软件的其他功能?如果有老师或者同学给出帮助,不胜感谢。

      材料插件是高级功能,我们只能提供最基本的技术支持。网上有个StepIndex的例子供参考

        谢谢孙老师的回复。这个例子我之前已经参考过了,不能完全满足需求。我再试试在此基础上做些改进。

      好的,再复杂的时变特性就需要自己开发了。建议你自己写Step这种插件,看看其结果与软件提供的是否一致,熟悉了整个流程再花时间开发新插件。
