optiFDTD怎样模拟光栅啊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.  (a)
