Subscriber老师同学们好,为了增加超表面的对称性,实现单元柱呈圆形分布,所以需要单元的衬底为六边形结构,希望大家能提供一些建议和思路,感谢!

Ansys Employee"所以需要单元的衬底为六边形结构",如果基底都是均匀的,只是上面的立方体尺寸和方位不同,应该是没有必要用六角形基底。
如果因故必须,带六边型基底的情况下周期就不是矩形的,你需要参考光子晶体带结构仿真的例子: Bandstructure of planar photonic crystal with a hexagonal lattice
我的直觉是不需要,除非基底本身的材料也在变化。普通超透镜应该不是这样的,因为制造要麻烦的多,除非是在微波段,尺寸比较大。不过这个时候仿真也可能有点问题,因为六角形需要至少5个这样的柱子才能形成长方体周期仿真区域。
我个人的直觉是,在光波段不需要。May 24, 2022 at 9:35 amSinhana
Subscriber你好,请问你的问题解决了吗,现在知道如何仿真六边形晶格的超透镜了吗,想向你请教一下

Ansys Employee参见上面回复,六角形需要想办法形成矩形来仿真单元,整体超透镜仿真与普通情况无异。Viewing 3 reply threads- You must be logged in to reply to this topic.
