Paper Abstract

By using a piecewise uniform approximation method, the reflectance and transmittance of light for an obliquely incident circularly polarized plane wave on a tilt-modulated chiral sculptured thin film (STF) were computed. The circular Bragg phenomenon was found to vanish when the amplitude of the modulation was high enough for oblique incidence. The tilt-modulated chiral STF then acts like a conventional mirror in the Bragg regime.
