关于弯曲波导(FEEM)的请教

      老师您好,我按照这个页面运行案例https://optics.ansys.com/hc/en-us/articles/4409707153811-Bent-Waveguide-FEEM-

      在第二步“As expected, the mode field has moved to the outside of the waveguide bend compared to the straight waveguide mode. The calculated effective index is 2.39784 + 7.89557e-06i with a loss of 278.001 dB/cm.”得到的并不是这个值,而是Effective index (mode 1): 2.3904 + 0i

      第三步也会报错“Error: E:/simulation/one/feem/waveguide_bend_radius_sweep.lsf line 33: all y matrix must have the same length”

      请问这个是怎么回事呢?我该怎么做呢?

      第二步问题是因为你没有设置为弯曲波导:

      bent_flag = true;

      run_feem_simulation;
      Effective index (mode 1): 2.39787 + 7.89995e-06i
      Loss (mode 1): 278.155 dB/cm

      第三步我测试没有问题:

        第二步我改成true了耶,但是我最开始打开文件时有提醒版本不够新,可能是这个原因吗老师?

      有可能的。请更新为最新版本。
