CHEMICAL SENSOR ELEMENT, SENSING APPARATUS, AND SENSING METHOD

摘要

A chemical sensor element contains a resonator having a first reflector in which particles of a fine metal structure are arranged two-dimensionally and periodically is counterposed with interposition of a dielectric layer to a second reflector, wherein the mode of the surface plasmon resonance excited in the metal fine structure is coupled with the mode of the resonator in which the entire of the first reflector is replaced by the metal thin film.
