文摘

The problem of the diffraction of the field of a plane electromagnetic wave by a metal nanocylinder with an arbitrary cross section is considered. Based on the discrete-source method, a comparative analysis of both frequency and spatial scattering characteristics is performed taking the nonlocal effect into account. It is found that nonlocality produces a substantial effect on the scattering characteristics. It is demonstrated that the use of the Drude model for a refractive index of plasmonic particles in the ultraviolet region may lead to erroneous results.
