Abstract

We demonstrate a convenient method to improve the surface Plasmon resonance sensitivity by manipulating the permittivity of active medium using metal-dielectric (Ag-SiO2) composite monolayer. We demonstrate the successful permittivity engineering of SPR active medium in both theory and experiments. Based on the basic theory of SPR and Bruggeman effective medium theory (EMT), we theoretically confirm that the angular sensitivity enhances using manipulated permittivity of metal-dielectric composite layer.
