摘      要：A strong coupling meta-diatom-plasmonic nanocavity is proposed and numerically *** the meta-diatomic sizes are gradually increased,the meta-diatomic electric dipole and quadrupole resonances could strongly couple to those of the *** characteristic anticrossing behaviors of three hybrid modes manifest the occurrence of the strong coupling from the transmission spectra,with Rabi-type splittings at about 40.8 meV and 128.4 meV for dipole interaction,and 11.8 meV and 72.7 meV for quadrupole interaction,*** also present the coupling strength dependence on meta-atomic positions,in which one meta-atomic position is fixed and the other is *** average Rabi-type splittings of three polariton modes are used to evaluate the coupling strength of the meta-atomic position *** corresponding Rabi-type oscillation in the time domain is also presented,which is obviously different from the one of a single meta-atom strongly coupling to a nanocavity.
