摘      要：We proposed a horseshoe-shaped nanostructure formed by etching a gap on a ring *** numerical simulations,it was found that the local field of the structure was significantly enhanced compared with that of the traditional ring ***,an additional resonant peak appeared corresponding to the electric field coupling in the gap,and this resonant wavelength was able to be tuned significantly by the particle size,gap size,and gap *** properties make the structure promising in biomedical and sensing applications.
