Light wave states in two-dimensional quasiperiodic media

Abstract

We study light wave behavior in two-dimensional quasiperiodic dielectric structures through the approximant ones. We show that, unlike the classic cases, light localization occurs in these structures due to local resonances in regions where scatterers form high-symmetry patterns, without involving any disorder. Moreover, introduction of disorder by structure randomization can lead to more extended states and a strong increase in light propagation.
