This work includes a theoretical study to design antireflection coating for mid-infrared region of electromagnetic
spectrum depending on characteristic matrix method using silicon (Si) as a substrate in order to coated by using Zinc
Sulfide (ZnS) and Cadmium Sulfide (CdS) as a low and high coating material respectively. The results shows that, for
the normal incidence, the reflectance of silicon reduced from (30.31) to (0.00049) when coated by three layer
according to the design [Air/LHL/Si]. Also the effect of angle of incidence on the reflectance spectrum of this design
are investigate. The results shows that the reflectance are increases with shifting toward shorter wavelengths.
