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?
jCa{WV:K} zV2c`he%z [s7I.rdGzz 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.
