Abstract

A design paradigm for Bragg multilayers made of columnar thin films (CTFs) is provided approximating both the ordinary and extraordinary refractive indexes of CTFs as Gaussian functions of the vapor incidence angle. Furthermore, we use a quadratic approximation of the same two quantities to design a cascade of chiral sculptured thin films (STFs) with successive pitches forming a geometric series to function as a wideband circular polarization filter.
