      我想请问一下用FDTD模拟oled时，是怎么计算light extraction efficiency的？我已经知道如何算power_radiated，但是我如果直接算power_radiated/dipolepower(f)，并且作图，就只能得到下面的结果，这个efficiency超过了1，我也不知道为什么

      现在这个问题已经解决了，然后我想问的是用dipolepower(f)/sourcepower(f)和用6个monitor组成的trans_box这个analysis group(是用transmission函数算的)算出来的光源发光功率怎么差了好几倍？这两个有什么区别吗

      sourcepower(f)是指偶极子在均匀介质无限大情况下的辐射功率；

      dipolepower(f) 是偶极子在有环境影响下的实际辐射功率。它受周围介质的影响。

      参见

        所以请问是怎么计算light extraction efficiency的？能给出案例吗？谢谢！

      请参考网上OLED仿真的例子，就是远场功率除以偶极子功率。

      一般需要多个仿真。
