Spectral Remittances of Chiral Sculptured Zirconia Thin Films in Non-axial propagation

TL;DR

This paper investigates the optical spectral properties of chiral zirconia thin films in non-axial propagation, revealing how azimuthal angle variations influence polarized reflectance spectra.

Contribution

It introduces a novel analysis of spectral remittances considering non-axial propagation and dispersion effects in chiral sculptured zirconia films.

Findings

First and second Bragg peaks observed in cross-polarized reflectances.

Azimuthal angle significantly affects linearly polarized spectra.

Circularly polarized spectra are less affected by azimuthal angle changes.

Abstract

The transmission and reflection spectra from a right-handed chiral sculptured zirconia thin film are calculated using the piecewise homogeneity approximation method and the Bruggeman homogenization formalism and considering that the dispersion of dielectric function happens in non-axial propagation state. First and second Bragg peaks were observed in cross-poloraized reflectances and it became clear that increasing the azimutal angle affects the spectra of linearly polarized state significantly. This is opposite to circularly polarized state.
