Design and Analysis of Plasmonic Structures Composed of Metal and Dielectric Nanoparticle Cluster

Abstract

Metallic structures in the nanoscale support the free-electron volatility of the conduction band under the name of surface resonance Plasmon. This happens when the radiant light strikes at a certain frequency. The study of the Plasmonic properties of nanoscale structures is related to the shape, size, and environment of the dielectric. In this study, we examine the effects of adding dielectric nano-particles on the Plasmonic properties of metallic nano-clusters with different structures. Carbon nanoparticles have been added in specific locations among the metal nanoparticles in these structures. These dielectric nano-particles have transformed the modes of Plasmon into magnetic plasmas. We can use these structures called metal dielectric. In order to increase the sensitivity of the sensors based on the exacerbation of local surface Plasmons, depositing dielectric nanoparticles between metallic Nano-disks with various configuration leads to metal-dielectric quadrupole Plasmon mode activation.
