    我是用optiFDTD模擬光柵的,現(xiàn)在在如何使用TF/SF產(chǎn)生斜入射平面波這個(gè)問(wèn)題上卡住了,請(qǐng)好心人幫幫忙啊。下面是官網(wǎng)給出的計(jì)算例子,請(qǐng)問(wèn)怎么能知道它如何設(shè)置的呢? y9 uVCR

    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. yV_ L/,6}D
