We study the coupling of localized surface plasmon and surface plasmon polariton modes in a system composed of a metallic nanoparticle chain imbedded in a dielectric–metal–dielectric substrate. The results show the influence of outside parts and imbedded parts of particles on the interaction between localized surface plasmon and surface plasmon polariton modes. An enhancement can be observed in our structure. This kind of the structure has a very promising candidate for biosensing and surface enhanced spectroscopy applications. |
