Аннотация:The problem of plane electromagnetic wave diffraction on an infinite plasmon nanocylinderwith a core-shell structure is considered. The solution is based on the computational scheme ofthe discrete sources method. This takes into account the presence of nonlocal effect in both coreand shell of the cylinder. Conjugation conditions accounting for plasmonic properties of metals areemployed as additional boundary conditions on the metal-metal interface. Numerical investigationof the nonlocal effect influence on the optical properties of cylindrical particles with their deformation is carried out.
