Abstract: Abstract: The effect of extraneous charge on the optical interactions with metallic nanoshells is studied theoretically based on an effective medium model, with the electrodynamic theory also formulated to justify the accuracy of this model. Both optical far-field and near-field interactions will be studied. Furthermore, the hybridization model is generalized to include the charge effects yielding results for the multipole resonances consistent with those from the effective medium model. It is found that while the extraneous charges will lead to blueshifted resonances, their effect on the bonding modes will be most significant, especially for localized near-field sources. In addition, it is pointed out that the applicability of our theory can go beyond the metallic nanoshell to include graphene-coated core–shell particles studied recently in the literature.
