Abstract
This thesis presents a novel plasmonic nanostructure design suitable for use in refractive index sensing applications. This design, called split ring nanosandwich, consists of a stack of two gold split rings separated by a SiO2 disk spacer where the gaps in the upper and lower split rings are in perpendicular axes. The optical properties of the structure are described using the plasmon hybridization picture. The strong hybridized modes obtained in this structure results in a high tunability of the optical response as well as strong field enhancement. Its refractive index sensitivity reaching 3024 nm/RIU
