ABSTRACT:
A metal such as Au and a dielectric such as borosilicate glass are simultaneously sputtered to form a film on a glass substrate. Next, this film is heated to grow metal particulates. Next, the substrate is drawn on heating to give an anisotropy to the metal particulates and produce a polarizer. The metal particulates are spheroidal and are dispersed almost homogeneously in the dielectric.
