Abstract—A method is proposed for calculating the optical resonance properties of metal–dielectric core–shell nanoparticles with an arbitrary number of layers in the shell. A formula is calculated for a particle with a single-layer shell, which confirms the well-known experimental and theoretical result. A formula is derived that relates the polarizability of a particle and its optical properties for the structure of a core with a spherical double shell.
