Abstract
We study plasmon resonances, which arise in the two-dimensional problem of diffraction of a plane wave on a gold cylinder with an elliptical shape of the transverse cross section. Numerical and asymptotical methods are used to find scattering and absorption spectra in the visible range. A simple analytical solution of the problem is found for a cylinder with an elongated shape of the transverse cross section. It is shown that in the case of normal incidence of a plane wave, a single quasistatic plasmon resonance is excited in such a cylinder.
