In simulation, the SWMS on ZnS are intended to research the broadband antireflection performance in the spectral variety of 1-13 μm by using FDTD approach. The perfectly matched layer boundary condition is used from the route of the beam propagation (z direction). However, the periodic boundary situations are established in https://zionfmprr.theisblog.com/28315353/detailed-notes-on-zinc-sulfide
