Abstract: 

Cylindrical sensors of noble metals exploiting the plasmon surface resonance are widely used in the bio-medical research and environmental studies and studying their characteristics in different wavelength bands is an actual task. We analyze scattering of a plane H-polarized electromagnetic wave in the visible range of wavelengths by a silver nanocylinder with a concentric dielectric coating. The arising plasmon resonances are treated using both the conventional classic presentation of the spatial distribution of the field amplitude nearby the object and by the spatial distribution of the Umov-Poynting vector. We demonstrate that plasmon description by the Umov-Poynting vector has obvious advantages, as the standing and traveling waves become clearly visible while the boundaries of the objects are evident in the spatial distribution. A paradox influence of the dielectric constant of the coating on the type of the plasmon resonance and spatial field distribution is illustrated.
Keywords: electromagnetic wave scattering, plasmon resonance, Umov-Poynting vector
