摘要：
The main aim of this work is to design and analyze a highly sensitive and miniaturized plasmonic ring resonator biosensor. Enhancement in field confinement due to plasmonic effect results in a considerable field confinement at the interface between metal (gold) and dielectric i.e. in the slot region. Hence, for this structure an average index sensitivity of 860 nm/RIU has been observed. Finite Element Method has been used for designing and performance analysis, investigated for the biological refractive index window of 1.34-1.35.
