Modeling the optical properties of gold
nanodisks with two holes
Abstract
Localized surface plasmon resonances in
gold nanodisk of 300x400 nm, 20 nm thick and with two 140 nm holes have been
investigated by numerical modeling. The modes excited by longitudinal and
transverse-polarized light, are observed. The refractive index sensitivity of
low-energy dipolar mode is higher for longitudinal light polarization and reaches
values of 1800 nm/RIU.
Key words: plasmonics,
optical biosensors, nanostructures, computer simulation of nanostructures.
