Abstract

In this work, we present an asymmetric transmission structure composed of a dielectric grating laying over a stack of several perforated metallic plates that operate at the extraordinary transmission resonance. The combination of the diffraction modes generated by the grating and the intrinsic dispersion of the stacked hole arrays (SHA) structure leads to exotic propagation regimes which include unidirectional propagation with sign-switchable refraction and deflection. Several coupling scenarios will be analyzed and then numerical simulations will be presented as well as experimental results in the V band of millimeter waves.
