      https://optics.ansys.com/hc/en-us/articles/360051107554-Tunable-CROW-Filter这篇案例中的第四步 根据耦合系数K确定gap，这个gap是指波导芯到芯的距离还是波导外壁间的距离？

      Lastly, FDTD simulations of the coupling regions will be used to determine the gap distances required to obtain the desired coupling coefficients ”κ1 and κ2”.

      所以它并没有定义Gap是哪里到哪里，关键是要得到合适的coupling coefficients ”κ1 and κ2”。
