The object of research is metal and composite nanoparticles of various shapes and metal-dielectric nanocomposites. Research methods – analytical, numerical modeling. The van der Waals interaction of metallic cylindrical nanoshells with parallel axes was investigated. A model was built to determine the frequency and size dependences of the heating of the medium surrounding a spherical bimetallic nanoparticle. The relationship for the frequency dependences of the diagonal components of the polarizability tensor of metallic cylindrical nanoshells and carbon nanotubes and the dimensional dependences of the longitudinal and surface plasmon resonance frequencies were obtained. The size dependence of the effective relaxation rate for a spherical metal nanoshell and the size-frequency dependence of the Parcell factor of the dipole in the vicinity of the shell nanoparticle resonator were obtained Product Description popup.authors Karandas Yan V.
