The mutual excitation rate and the radiative and nonradiative powers of bi-dipole in the presence of Ag NS were analyzed. Our results show that these modes are in accordance with the surface plasmon resonances of Ag NS irradiated by a polarized plane wave. In addition, the mutual excitation rate retains local maxima at these modes. Moreover, the quadrupole and octupole modes are only excited in the cases of the symmetric radial bi-dipole, while the dipole and sextupole modes are only excited in the cases of the antisymmetric ones. The dipole mode is broadband, while the other higher-order modes are narrowband. Moreover, all of these plasmonic modes are red-shifted as the ratio of the core radius to the shell thickness increases.
