Ansys Employee这个脚本是谁传给你的?
第一种方法是将出射光分解为左右旋分别计算,第二种方法是总的透射率。但是这种归化除以0.093是否合适我就不知道 啦。
你用的是平面波吗?如果是高斯光束透射率一般固定,如果用平面波和TFSF,结果的确需要修正,如何修正,那就是各显神通了。

Subscriber这是我根据官网上对透过率的定义自己修改的。
我使用的是平面波,仿真区域相比于超透镜的尺寸要大很多,删除所有结构后,在光源下端直接放置一监视器,计算了和超透镜等大的区域的光透射率为0.093(等效为超透镜面积和整个仿真区域面积的比值)。因此实际入射到超透镜的能量是sourcepower×0.093,在计算聚焦效率是用的焦平面的能量除以这一值。这种修正方式是不合适的吗?请问老师还有其它修正方式吗?

Ansys Employee如前所说,如何修正,那就是各显神通了。因为使用平面波和PML,有衍射,仿真和平面波尺寸改变如果结果不变化,或者变化很小,我个人认为这种修正就算合适。
