摘要：

A unique metal-dielectric structure composed of symmetric multilayered nanocylinder is demonstrated to support unconventional superradiant and subradiant plasmon modes. Here, the twin distinctive dipole-dipole Fano resonances are observed in the structure within the visible spectrum by carefully selecting the geometrical parameters. The spectral features of these Fano resonances are controlled by changing the incident field polarization and parameters of the nanoparticle. Eventually, an RLC circuit model is proposed to reproduce the optical response of the nanostructure.
