A new configuration for metasurface construction is presented to exhibit potential multi-functionalities including perfect absorption, bio/chem sensing, and enhancement of light-matter interaction. The reciprocal plasmonic metasurfaces discussed here are composed of two plasmonic surfaces of reciprocal geometries separated by a dielectric spacer. Compared to conventional metasurfaces this simple geometry exhibits an enhanced optical performance due to the hybrid plasmonic-photonic cavity. The discussed reciprocal metasurface design further enables effective structural optimization and allows for a simple and scalable fabrication. The physical principle and potential applications of the reciprocal plasmonic metasurfaces are demonstrated using numerical and analytical approaches.
