Abstract:   (425 Views)
 
Nowadays, metal nanoparticles have been considered due to their desirable optical properties, and several methods have been developed for their fabrication and use in various devices. Surface plasmons are mass fluctuations of electrons in metals that can be excited by electromagnetic waves, which are a major component in routing and determining optical properties at the nanometer scale. In this study, the optical properties of a multilayer structure consisting of an array of nanoparticles located on a dielectric substrate are also factors affecting the increase of optical absorption. The optical properties of nanoparticles depend on the material, shape, size and dielectric environment, and various factors such as nanoparticle diameter, incident radiation angle and distance between nanoparticles affect the absorption improvement that has been investigated.
