您好，目前没有相关示例演示与参考资料，具体计算方式建议通过外网查阅。

中极化激元的能带，这是一个光子晶体叠加TMDCs单层膜的结构，我在过渡边界条件中定义TMDCs的色散，计算结果并不正确。过渡边界条件是否不适用于计算特征频率？

您好，理论上可以通过定义与场有关的多极展开公式实现，可参考如下多极展开的案例：//www.denkrieger.com/model/multipole-analysis-of-electromagnetic-scattering-31901

您好。这篇博文只讨论了石墨烯的光电学性质。如果要在传热模块中模拟石墨烯的话，您需要先在论文文献中找到描述石墨烯热学性质的模型，然后输入COMSOL软件中进行模拟。石墨烯的热学性质被研究得比较透彻了，应该有很多相关的文献可以供您参考。

您好。对于非线性问题，您可以参考以下两个例子（一个使用频率，一个使用时域）：
https://www.comsol.com/model/second-harmonic-generation-in-the-frequency-domain-24151
https://www.comsol.com/model/second-harmonic-generation-of-a-gaussian-beam-wave-optics-14701
这篇博文中介绍的石墨烯性质只包括线性电导率，如果要模拟非线性效应的话需要做额外的考虑。
