Refractive index sensing with localized plasmonic resonances
Theoretical description and experimental verification
Autoren
Mehr zum Buch
The book explores the sensing capabilities of plasmonic resonators in response to changes in the surrounding refractive index. It presents a comprehensive theory that links the resonators' electrodynamic properties, such as resonance wavelength and electric field distribution, to their sensitivity. A figure of merit (FOM) is introduced, accounting for noise and determining the measurability of refractive index changes. Theoretical bounds and scalings in the quasi-static limit are derived, supported by numerical calculations and experiments with crescent-shaped resonators, demonstrating strong alignment with the theory.
