Angular selective optical transmittance through Cr-based films made by oblique angle sputtering: experiment and theory

Abstract
Sputter deposition of Cr, with oblique incidence of the species towards a substrate, has been used to produce films with angular selective optical transmittance. Multiparameter fits, embodying the Bruggeman effective medium theory applied to an anisotropic medium of Cr and voids, were able to reproduce the optical data.
