摘要

Presented is a mathematically convergent method of calculation of 3-D electromagnetic wave scattering by metal nanoparticles in the optical wavelength band. The method is based on solving the set of the Muller boundary integral equations (IEs). The formulas are derived for the components of optical theorem: total scattering cross-section (TSCS) and extinction cross-section (ECS). Sample results of calculation of these characteristics are shown for various angles of incidence and polarization of a plane electromagnetic wave on a nanoparticle having two different shapes and electric sizes. These results demonstrate the resonances on the surface-plasmon (SP) modes at certain wavelengths.
