In this paper, we calculate the extinction spectra and the distribution of electric near-field of the nanoparticles which are embedded a disk in a hollow square structure through using the discrete dipole approximation method, and compare our results with extinction spectra and the distribution of electric near-field of the single hollow square nanostructure. The research results show that a new resonant mode, which is located in the traditional excitation wavelength range of surface enhanced raman scattering, can be produced due to the coupling interaction. Then, we can use this mode to meet the shortage of the hollow square nanostructure fabricated by nanoskiving. In addition, the surface plasmon resonance peak can be tuned by changing the shape parameters of the silver nanoparticle. These results can be used in Raman scattering, molecular biological, and chemical detection.
