Subscriber老师您好,
请问FDTD中监视器里E-field中的vector可以看做成是偏振的方向吗?
以及为什么无偏振入射时候箭头是45°倾斜的是正确的吗?

Ansys EmployeeFDTD中监视器里E-field中的vector应该可以看做成是偏振的方向,因为它使用实部作图的。
无偏振入射?不知道你怎么定义无偏振,一般都是由偏振的,要实现非偏振光至少需要两个仿真才能得到:https://support.lumerical.com/hc/en-us/articles/1500006149562-Polarization-incoherence
两个光源叠加,偏振角差90°,这就是45度的线偏振啊,你找教科书看看。
如果是偏振方向一样,位相差90度,只是相当于有个初位相,也不会形成“无偏振”。请普及一下此概念在定义。March 11, 2022 at 1:36 am1996lhl
Subscriber谢谢老师的及时提醒。
此外,我发现很多的帖子里的图片都打不开。相应的文件都无法下载,请问老师这个问题会不会逐渐被修复。
就像您提到的这个网页里的图片和文件都打不开/下载不了。不知道目前用什么办法可以查看和下载呢?

Ansys Employee官网上的所有图片和文件只要注册都应可以下载;图片个别情况下下可能缺失,发现的话请告知。
官网注册与论坛注册不同。
如果是网页无法加载,一般是网络问题,找网络不挤的时候试一下。因为这个是国际网站,有些单位仅国内网站优先。Viewing 3 reply threads- You must be logged in to reply to this topic.
