Abstract

Mathematical simulation of the optical nanoantenna based on a comb-like finite nanostrip grating is presented. It is carried out using the generalized (effective) boundary conditions (GBCs) imposed on the strip median lines and the Nystrom-type discretization of the relevant singular and hyper-singular integral equations (IEs). Associated scattering and absorption spectra are computed and both surface plasmon resonances and periodicityinduced effects are analyzed.
