In simulation, the SWMS on ZnS are designed to analyze the broadband antireflection performance in the spectral selection of one-13 μm by using FDTD system. The perfectly matched layer boundary situation is used inside the direction from the beam propagation (z direction). Nevertheless, the periodic boundary ailments are established in https://infrared-zinc-sulfide74062.ezblogz.com/59762696/the-infrared-zinc-sulfide-diaries
