老师,您好。FDTD中simulation bandidth和source中wavelength区别在哪里,仿真根据哪个进行?

      您好
      simulation bandwidth 的作用在於兩個地方,其一是固定材料擬合的波長範圍,其二是使用這段波段來安排網格大小。
      例如說simulation bandwidth 為0.5~0.8,而source為0.4~0.9。
      雖然光源波長是0.4~0.9,但材料擬合會以0.5~0.8為主,而網格大小也是由0.5~0.8決定。
      這個功能對於掃波長的模擬很有幫助,因為無論光源波長怎麼改變,材料擬合和網格大小都是一樣的。
      可以參考這裡
