ANGULAR SELECTIVE OPTICAL TRANSMITTANCE THROUGH CR-BASED FILMS MADE BY OBLIQUE ANGLE SPUTTERING - EXPERIMENT AND THEORY

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