Bandgap extension of disordered one-dimensional metallic-dielectric photonic crystals

Photonic crystal (PC) with a photonic band gap (PBG) has attracted much attention since the initial predictions of Yablonovitch and John. This active research area has been extended to frequency-dependent metallic-dielectric PC (MDPC) theoretically and experimentally in Keskinen, M.J., et al, (2000). In this paper, the PBG properties are investigated by transform matrix method when disorder is introduced in the one-dimensional (1D) frequency-dependent MDPC.
