Abstract:We theoretically demonstrate a high-Q and intense lattice plasmon resonance supported by the hexagonal nonclose packed thin silver nanoshells array. By introducing the diffraction coupling mechanism, the high-Q and intense lattice plasmon mode stemmed from the coupling between the TM 1 cavity plasmon mode and the diffraction mode of the first-order Wood anomaly is obtained in the thin silver nanoshells array, successfully solving the trade-off between the Q-factor and the resonance intensity of the cavity plas… Show more
