A composite nanobowtie with Ag/SiO2/Ag sandwich structure is presented and its optical properties especially the Plasmon property are studied using the discrete dipole approximation (DDA) method in this paper. Our results show that this structure has simply-tunable surface Plasmon resonance (SPR) wavelengths and more "hotter spots" provided by the sandwich structure, as well as the remarkable enhancement of the localized E-field provided by the bowtie structure. The transverse and longitudinal Plasmon coupling mechanism is employed to explain tunable SPR and strong E-field enhancement respectively. The sandwich nanobowtie possesses the qualities of simplytunable SPR and great E-field enhancement, thereby holding a great potential in applications such as surface-enhanced Raman scattering (SERS).
