Abstract :
The model for the optical response of composite metal-dielectric nanorods located on the surface of dielectric, based on a self-consistent analytical approach is proposed. The absorption of evanescent TE-polarized waves under Otto configuration is studied theoretically in the frame of the effective susceptibility concept. A possibility of an effective control of absorption of TE waves by tuning the height of the plasmonic cap is investigated. Configurational resonances are considered as a probable physical explanation of an origin of the absorption peaks caused by the TE-surface wave excitation.
