Abstract: The interaction of light with the localized-delocalized system, i.e., a metalsurface with rectangular cavities of finite depth, has been studied. Reflectionspectrum has been measured in the optical frequencies and resonant minima havebeen observed. We have developed an analytical model, which agrees well withthe experiment. The localized waveguide resonance and delocalized surfaceresonance have been identified and discussed. The results may be useful formanipulating the coupling between light and matters.
