    Multiple surface lattice resonances generated with noble metallic nanoparticle array can be used to suppress radiative losses around several spectral positions, enlarge the resonance quality factor, and enhance the localized near-field intensity. This study proposed a method to generate multiple surface lattice resonances with noble metallic split-ring resonator arrays. It shows that for the magnetic dipole resonance, the generated equivalent magnetic dipole is oriented perpendicular to the paper plane, and the scattering fields are propagating along x and y directions, which makes it possible to realize the coupling between the magnetic dipole mode and the Rayleigh anomaly along both directions. The calculation results indeed reveal that the coupling between the magnetic dipole mode and the Rayleigh anomaly leads to the formation of a sharp surface lattice resonance, and double surface lattice resonances are generated when the lattice spacing are different with each other. Furthermore, the similar optical response can be obtained with electric quadrupole resonance of the split-ring resonator. These properties make split-ring resonator arrays promise for the design of micro/nano photonic devices.
