Paper Abstract

We report on the propagation of plane electromagnetic waves through a complex dielectric medium consisting of two complementary grating structures: a sinusoidal interface between two isotropic dielectric mediums overlaying a structurally chiral anisotropic dielectric medium. Phenomenons characteristic of both types of structures - namely the Rayleigh-Wood anomalies and the circular Bragg phenomenon - are shown to co-exist, even at wavelengths where both occur together. Our results open the possibility of novel device geometries which exploit these effects.
