Abstract

An approach to describing of the excitation and propagation of the surface plasmon polaritons (SPPs) along the surface with the nanodisks that are located above them is proposed. In the framework of the proposed approach the dissipation function is calculated for the different geometry of the systems with the disks. The Fano-like antiresonance curves of absorption profiles have been obtained. The antiresonance absorption characteristics have been explained by the interaction between the SPP with the continuous spectrum and localized plasmon polaritons at the cylinders with the discrete spectrum. The obtained result is similar to the well-known Fano effect.
