    我是用optiFDTD模擬光柵的,現(xiàn)在在如何使用TF/SF產生斜入射平面波這個問題上卡住了,請好心人幫幫忙啊。下面是官網給出的計算例子,請問怎么能知道它如何設置的呢? ,&t+D-s<f

    When a tilted plane wave is launched to the layout, the time domain wave propagation can be observed in the simulator. OptiFDTD uses the Total-Field/Scattering field (TF/SF) algorithm for the input wave excitation.  This TF/SF technique has the pure reflected wave and transmitted wave in the same simulation[1].  Figure 3(a) is the plane wave response before it accesses the grating surface.  Figure 3(b) shows the time domain scattered field, diffraction field and transmitted field. d/7fJ8y8
