Abstract
Optical properties, reflectance and transmittance, of couple inverse conical helix sculptured thin films are investigated using a combination of local homogenization and transfer-matrix method and are compared with a normal chiral one. Varying radius, the major conical helix characteristic, contributes to circular Bragg phenomenon (CBP) in a limited range of wavelengths, not continuously but discretely. These discrete high-reflection regimes in the proposed structure are narrower in comparison to those in fixed-radius structures. The effect of engineering structural parameters, including radius variations and loops making the structure, on peaks’ quantity and intensity and on bandwidth of spectrum in which the CBP occurs have been investigated.
