如何计算某一模式的功率在某一特定区域内的部分在其总功率内的占比

      尊敬的工作人员你好。

      不知道怎么搞的,上传不了图片。我的诉求是想求某个模式的功率在特定区域内,比如说SOI脊波导的基模在脊波导区域内的功率占比。这该使用什么方式去获取呢?

      首先你会计算功率吧?参见 

      Ansys Insight: FDTD 初学者: transmission函数的使用、透射率反射率正负号问题

      你只需要再积分脊波导区域内的功率,方法是建立一个矩形函数,乘上原来的坐标。比如

      original coordiate x (nx points);

      rentangle for the ridge region xmin xmax.

       x=getdata("monitor","x");
      xmin=-0.1e-6;xmax=.1e-6;
      xnew=(x>xmin)&(x

      同理再给出ynew,然后用(xnew,ynew) 做功率积分即可。

      你试一下。
