In order to investigate the coupling effect of the two-layer array and the resulting upper and lower ring dipole modes, a microwave method was used to introduce a split resonant ring array structure in which the intermediate separator and the upper and lower surface were placed. Firstly, the upper ring dipole mode of the structure is excited by microwave, and then the dielectric plate is coupled to the lower ring dipole to realize the ring dipole cascade coupling, by adjusting the resonant ring up and down the number of array, the size of the resonant mouth, as well as the change of the medium plate in the middle of the dielectric coefficient. The excitation and coupling effects of ring dipoles in artificial localized surface plasmas by microwave frequencies can be studied. The results show that this mode can produce multi-peak ring dipole effect, which enriches the understanding of the coupling effect between artificial local surface plasmon ring dipole modes, and lays a foundation for the design and application of new sensors.
