Localized surface plasmon resonances in gold nanodisks with two holes have been investigated by numerical simulations. The longitudinal and transverse modes have been observed upon illumination with polarized light. The estimated refractive index sensitivity of low-energy dipolar mode is higher for longitudinal light polarization and reaches values of 1800 nm/RIU.
