Sharp dark-mode resonances in planar metamaterials with broken structural symmetry

Abstract

We report that resonant response with a very high quality factor can be achieved in a planar metamaterial by introducing symmetry breaking in the shape of its structural elements, which enables excitation of dark modes, i.e. modes that are weakly coupled to free space.
