A silver nanostructure consisting of double sectors is proposed in this paper. In addition, the plasmon resonance and electric field enhancement have been investigated theoretically. It is found that, in this structure, the multiple resonances produce, which is tunable by the parameter of the structure. The localized electromagnetic fields can be produced at the tips of the structure. In addition, the enhanced electromagnetic fields can be observed between the sectors in a wide scale at the lower energy peak. The result of the investigation has great significance for the production of practical nanostructures and the improvement of possible applications.
