Subscriber手性介质的本构参数是频率相关的,它们的本构关系表现出磁电耦合。因为频率色散的建模需要修改FDTD模拟的时间部分,而磁电耦合需要修改空间部分。所以我们在使用FDTD仿真过程是否可以修改FDTD内部有关电场和磁场的公式呢?

Subscriber理解上是可以通過客製物理結構和材料屬性來達到建模和仿真的效果,例如說是下面的例子:

https://qspace.library.queensu.ca/bitstream/handle/1974/15343/Cartar_William_K_201701_MASC.pdf?sequence=3

如果有更多細節會更容易解答此問題,謝謝。

Ansys Employee”因为频率色散的建模需要修改FDTD模拟的时间部分,而磁电耦合需要修改空间部分。所以我们在使用FDTD仿真过程是否可以修改FDTD内部有关电场和磁场的公式呢?”
频率色散有不同定义吧?这里是指什么?指不同频率的产生的信号延迟,还是材料色散,还是其它?
修改空间的哪个部分?
目前的材料插件可以实现对原始迭代仿真的修正,其它只能靠材料拟合。
请再考虑,如果必要请给出更多信息。
此外,论坛主要目的是现有算法的讨论,对新的目前没有的功能,只能提供有限的帮助。
以后请发中文论坛 https://forum.ansys.com/forums/forum/discuss-simulation/photonics/photonics-chinese/

Subscriber我们在建模型的时候需要添加一层手性介质层材料(如生物分子),这种材料在材料库里面没有,我们需要重新引入该手性介质的手性参数(具有实虚部),然后在模拟时,改手性介质层会与我们的金属纳米结构进行相互作用,势必会引起电磁场的变化,在这里我们就需要在电场和磁场的公式中添加这样一个手性参数,也就是说我们想要去修改软件内部电磁场的本构方程。我想请教一下我们是否可以去修改软件中的自带公式呢?
