Electromagnetic wave scattering by periodically structured chains of closely spaced sub-wavelength wires

Using the field expansions in local coordinates and addition theorems for cylindrical functions, we consider the problem of the H-polarized waves scattered by finite chains of circular wires. The scattering and absorption cross-sections are found numerically and localized-plasmon and periodicity-caused resonances are studied for the visible light scattering by the grids of closely spaced nanowires made of silver.
