Abstract
The classical electromagnetic scattering theory for a circular cylinder that is irradiated by a normally incident plane wave is extended to the case of a spatially dispersive cylinder. A dielectric constant that applies in the vicinity of an excitonic spectral line is used, and the size quantization of the exciton motion is taken into account through the boundary conditions that are employed at the surface of the cylinder. Examples of calculated extinction spectra are presented, and it is found that the excitonic absorption peaks shift to higher energies with decreasing cylinder radius.
