Periodic structure assemblies are provided. An example assembly includes: a dielectric layer having a top and a bottom; a first frequency selective layer disposed on the top of the dielectric layer, the first frequency selective layer having a plurality of electrically conductive elements arranged as a first periodic structure; and a second frequency selective layer disposed on the bottom of the dielectric layer, the second frequency selective layer having a plurality of electrically conductive elements arranged as a second periodic structure. Another periodic structure assembly includes: a substrate; and an array of periodic elements defined by a contiguous trace of conductive material supported by the substrate, each of the periodic elements exhibiting side walls, with each of the side walls having an inwardly extending protrusion.
