Subscriber请问那个可以反映反射强度?怎么表示,比如正比还是公式什么的?

Subscriber还有模型是光栅的反射率监视器得到的反射率是衍射效率吗?

Ansys Employee根据你的提问,估计还是新手,请多学习网站上的内容和视频。
你可以加监视器记录整个传播面的情况,看看哪里是反射光,哪里是透射光。一般较少用场,而是用透射率。如果是光栅,需要用光栅函数计算不同衍射级的衍射效率,参见 Ansys Insight: 关于光栅衍射级及其计算

Subscriber老师 如果用场的话?那个可以表示光场强度?

Ansys Employee光场强度,看你怎么定义了:
1: 光学强度参见 Ansys Insight: 光学强度、功率、电场强度平方的关系以及电磁能量
2:电场绝对值平方,即 abs(E)^2。你可以从监视器里用这个脚本直接得到:
E2=getelectric("monitor_name","E2");
或者得到E的Dataset后,可以用
Edataset=getresult("monitor_name","E");
E2=Edata.E2;
或者直接将E的三个分量直接绝对值平方相加。September 2, 2021 at 8:52 amSeptember 2, 2021 at 3:56 pmGuilin Sun
Ansys Employee颜色代表对应的Magnitude,即大小。这个与Matlab是意义的,做彩色的意义就是用颜色代表大小。请参考一些网上的视频,比如优酷网(多数为中文视频)和官网上的EDU视频。你画的箭头显然代表距离,坐标已经给显示了。Viewing 8 reply threads- The topic ‘您好老师 请问功率监视器中E、H、P、grid分别指的是什么,我点开了E,有什么作用呢?’ is closed to new replies.
