ABSTRACT

In this work we have studied the effect of interfacial layer on the refractive index, and propagation of waves in small spherical metal/dielectric composite separated by interfacial layers which is randomly embedded in a linear dielectric host matrix. The theoretical, and numerical descriptions are in terms of the interfacial factor (I) by incorporating Taylor expansion and Drude model. The result shows that both the interfacial layer property, and the percentage of the volume fraction of the metallic particles in the composite has an effect on the refractive index, and propagation of waves of the composite when the dielectric functions of the interfacial layer is more metal-like property than dielectric-like property.
