Polarizability spectra of magnetized layered nanocomposites with an anisotropic core or cladding and localized surface plasmons

摘要

This paper discusses the dynamic polarization properties of layered spherical and cylindrical composites with core-cladding structure, located in a constant magnetic field. The current-carrying component of the nanostructure can be either the central core or the cladding composed of a diamagnetic metal. It is shown that the presence of an external magnetic field modifies the polarizability spectra of the nanosystem, thereby altering its optical characteristics. The dipolar polarizability spectra of a composite nanocylinder with an excitonogenic cladding are constructed, as well as those of a layered spherical particle of the same structure with pronounced exciton-plasmon interaction.
