Abstract
The propagation of s- and p-polarized light through quasiperiodic multilayers, consisting of layers with different refractive indices, is studied by the transfer matrix method. In particular, we focus on the transmission coefficients of the systems and their dependence on the incidence angle and on the ratio of the refractive indices. We obtain additional bands with almost complete transmission in quasiperiodic systems at frequencies in the range of the photonic band-gap of a system with a periodic alignment of the two materials for both types of light polarization. With increasing incidence angle these bands bend towards higher frequencies, where the curvature of the transmission bands in the quasiperiodic stack depends on the metallic mean of the construction rule. Additionally, in the quasiperiodic systems for p-polarized light the bands show almost complete transmission near Brewster's angle, in contrast to the results for s-polarized light. Further, we present results for the influence of the refractive indices at the mid-gap frequency of the periodic stack, where the quasiperiodicity was found to be most effective.
