Abstract
Discriminatory optical behavior of obliquely deposited films with respect to the polarization of light has been known for about a century.1 Although scarce, reports on this effect can be found in the literature from the early2-5 and mid6-8 1900's. More recently, metal films were used as polarizers in the near-infrared9 and dielectric films were shown to perform as phase-retarders in the visible.10 Those are two different manifestations of structure-induced optical anisotropy in connection with significant asymmetries in extinction coefficient and refractive index valves, respectively.10
