Abstract
We present the results of numerical simulation of the scattering and absorption of the H-polarized electromagnetic wave by several discrete scatterers made of silver nanowires in visible range. Using the Fourier expansions and addition theorems for cylindrical functions, we perform analytical regularization and obtain a block-type Fredholm second-kind matrix equation for the scattered-field expansion coefficients. This guarantees the convergence of numerical solution. Numerical results are presented of the analysis of far-field and near-field characteristics of the studied scatterers. It reveals the presence of the grating and the plasmon resonances in the far-field characteristics and specific near-field patterns in these resonances.
