Nanospheres are widely used as the substrates for surface enhanced Raman scattering (SERS). In order to further enhance the electric fields around nanospheres and improve the SERS intensity, in this paper, we introduce a novel nanostructure which is composed of a couple of parallel clapboards and a clamped nanosphere. The discrete dipole approximation calculation results indicate that when the parallel clapboards are used, the electric fields around the nanosphere are much enhanced. Therefore, the nanospheres clamped by parallel clapboards may work well as the SERS substrates. In addition, the effects of the structural parameters of parallel clapboards are also investigated.
