✦ Synopsis

A stepwise chirping of the periodicity of a chiral sculptured film is shown to considerably enhance the bandwidth of the Bragg regime, thereby extending the frequency range of operation as a circularpolarization filter.

## Abstract Chiral sculptured thin films (STFs) are periodically anisotropic, and exhibit the circular Bragg phenomenon over a certain wavelength regime on axial excitation. Among the key deposition parameters for the growth of a chiral STF is the so‐called vapor incidence angle Ο‡~__v__~. Analysis

## Abstract The Bragg wavelength regime of an axially excited, chiral sculptured thin film is shown to contain resonances of electric, magnetic, and mixed types. The resonance wavelengths initially change rapidly, but later stabilize, with respect to the film thickness. The center wavelength of the
