In simulation, the SWMS on ZnS are created to analyze the broadband antireflection efficiency in the spectral range of 1-13 μm by utilizing FDTD technique. The perfectly matched layer boundary situation is utilized inside the direction in the beam propagation (z direction). Nonetheless, the periodic boundary problems are established in https://zincsulfide53074.life3dblog.com/27554893/5-simple-statements-about-zinc-sulfide-explained
