Subscriber老师您好,我最近在做双层涡旋超表面的仿真。两片超表面是共轭的,相位相反。这是建模时使用的脚本程序。

Ansys Employee我不太清楚这两个超表面是怎么在仿真中出现的。 光源距离超表面前面的距离相等吗?超表面的后表面到监视器距离完全一样吗?如果一个超表面的前表面是第二个超表面的后面,也就是前后反转的话,那结果就不会想等。
当然,还要保证两个仿真的一切设置,特别重要的是网格不变。如果结构单元有所变化,那必须用Override均匀网格,保证两个仿真的网格一点不变。
你再检查一些。
此外,以后写中文请发中文论坛: Photonics - Chinese — Ansys Learning Forum

Subscriber非常感谢老师的耐心回复。第一次使用论坛没有注意发帖的位置,十分抱歉。
我仔细检查了两个单层超表面的仿真,设置是完全相同的。为了保证不受其他因素影响,我直接仿真了一个双层的超表面。可以看到每个柱子的旋转角度都是相反的,按照几何相位的理论,相位只与纳米柱的旋转角度有关,那么产生的相位叠加起来应该为0,但是事实却并不如此,February 14, 2022 at 4:15 pmGuilin Sun
Ansys Employee那现在主要是要在超表面设置固定网格,即Override试一下。
如果还有问题,建议重新建立新的Project,吧所有结构监视器光源拷贝过去,但是不要拷贝FDTD和网格,后者另行设置。仿真一个以后,把结构删除,把另外一个结构拷贝过来。保存为另外的文件名。
拷贝用Ctrl^C粘贴用 Ctrl^V。你试一下Viewing 3 reply threads- You must be logged in to reply to this topic.
