Post- versus pre-resonance characteristics of axially excited chiral sculptured thin films
Abstract:Axially excited chiral sculptured thin films (STFs) are shown to exhibit the circular Bragg phenomenon in the pre-resonant (long-wavelength) regime but not in some parts of the post-resonant (short-wavelength) regime. Chiral STFs act as very good polarization-independent reflectors in the vicinity of material resonances in the latter regime.
