摘　　要：We present three important extensions of the plasmon hybridization(PH)method:a generalization of the method to include realistic non-Drude dielectric permittivities for metals,the development of an algorithm for the calculation of plasmon-induced electric field enhancements,and the extension of the PH method to the modeling of plasmonic Fano resonances.We illustrate these developments with an application to a silver nanosphere dimer and a symmetric silver nanosphere heptamer.We present three important extensions of the plasmon hybridization （PH） method： a generalization of the method to include realistic non-Drude dielectric permittivities for metals, the development of an algorithm for the calculation of plasmon-induced electric field enhancements, and the extension of the PH method to the modeling of plasmonic Fano resonances. We illustrate these developments with an application to a silver nanosphere dimer and a symmetric silver nanosphere heptamer.
