Аннотация: In this paper, the problem of diffraction of a plane electromagnetic wave on an infinite layeredmagnetoplasmic nanocylinder is considered. The resulting effects of spatial dispersion in a gold shell, also known as nonlocality effects, are taken into account within the framework of the theory of the Generalized Nonlocal Optical Response. Based on the new scheme of the discrete source method, the influence of particle deformation and the effects of spatial dispersion on the position and amplitude of the maximum energy absorption is analyzed. It is shown that the maximum position can be shifted to the region of transparency of human biological tissues due to variations in the thickness of the golden shell and the core material. It is established that accounting for the spatial dispersion in a metal shell leads to a decrease in the absorption intensity and a shift of the maximum position to the short-wavelength region.
