Ansys Employee不一定是不该出现的,需要多做分析。
一种情况是能带含有另外偏振结果:电场可以垂直于纸面,也可以平行于水平线。你可以控制电场偏振试一下,但是不一定能完全解决,因为偶极子近场各个方向偏振都有,强弱不等而已。
如果的确不该出现此能带,很可能是监视器并没有监测到最强的谐振。你可以选需要能带上的几个频率点,加频域监视器看看这些波长的最强点在什么地方,修改分析组中时间点监视器的位置,使得它们位于不同波长的最强点看看。同时修改偶极子位置,使得它们也位于不同波长的最强点,以最大限度地激发能带上的模式。
这些方法不是很容易,你试一试看看吧。

Subscriber孙老师,我是和咱们之前的视频上一样,使用的平面光源激发,使用平面光源指定偏振方向后是否也会激发不同方向的偏振哪

Ansys Employee衍射以后偏振可以改变。
建议你用多个模式光源(含高阶模)激发试一下。
