Effective Dielectric Constant of periodic Composite Material with spherical Inclusion

Abstract

We have studied the optical properties of nanospherical metal inclusions in dielectric host matrix. Both analytical and numerical methods are employed for analyzing this nano composite system. The real and imaginary part of the dielectric constant, refractive index and absorption coefficient the composite system as a function of the concentration of nanospherical metal inclusion is investigated. The result indicates that the magnitude of these optical constants are amplified with an increment of concentration nanospherical inclusions in the dielectric host matrix.
