Abstract

The goal is a coating composed of nonabsorbing layers that manifests relatively high reflectance at a wavelength λ₀ for the p polarization and low reflectance for s polarization, where the incident medium and substrate have an index of 1.52 and the incidence angle is 45°. In other words, the coating is in a cemented cube. Its design is where p is the number of times the basic period is repeated. H and L represent layers of optical thickness λ₀/4 (matched at 45°) and refractive indices n_h and n_L, respectively. The single layer in AR₁ dereflects at a wavelength λ₀ the interface between glass and a massive medium of index n_H for s polarization. The single layer in AR₂ dereflects at a wavelength λ₀ the interface between a massive medium of index n_H and a massive medium of index n_L for s polarization.
