In this paper, effects of adding dielectric nanoparticles into metallic nanocluster with heptamer configuration on their plasmonic properties have been investigated. Carbon nanoparticles inter metal nanoparticles are added in specific zones in the given structure. These dielectric nanoparticles make magnetic plasmon modes from ordinary plasmon modes. Metal-dielectric nanocluster structures are known to increase the sensitivity of sensors based on localized surface Plasmon resonances. Depositing dielectric nanoparticles between metallic nanodisks in the heptamer structure leads to metal-dielectric quadrupole plasmon mode activation.
Keywords: Plasmonic, Fano resonance, Heptamer, Carbon dielectric nanoparticle
