Plasmonic bilayers fabricated by depositing metal on nanopillar or nanocavity arrays are an effective solution for the industrial scale production of plasmonic templates. Such structures commonly consist of a disk array and a quasi-Babinet complementary perforated film comprised of holes, which are displaced vertically by the pillar or cavity.
