title: Sharp trapped-mode resonances in planar metamaterials with a broken structural symmetry.
abstract: We report that a resonance 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 trapped modes, i.e., modes that are weakly coupled to free space.
