[求助]optiFDTD怎样模拟光栅啊 [复制链接]

我是用optiFDTD模拟光栅的，现在在如何使用TF/SF产生斜入射平面波这个问题上卡住了，请好心人帮帮忙啊。下面是官网给出的计算例子，请问怎么能知道它如何设置的呢？ !(]dz~sM

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.
