A point matching method is applied to the problem of light scattering by non-spherical bodies. The electromagnetic field is expanded into a series of spherical waves which include all multipole terms which contribute significantly to the wavefield. We examine, in particular, the absorbance of light by a plasma particle and demonstrate the existence of various peaks associated with dipole and quadrupole resonances of the induced charge distribution.
