Ukrainian Journal of Physics| Резюме: | Expressions for the diagonal components of the Q-factor, local electric field enhancement, and polarizability tensors, as well as the absorption, scattering, and extinction cross-sections have been obtained for metallic dumbbell-shaped nanoparticles in the classical approximation. The equivalent-spheroid approach is used to develop an analytic theory. The calculation results for the indicated optical characteristics are obtained for dumbbell-shaped nanoparticles of various sizes and materials. The influence of the particle’s effective aspect ratio on the frequency dependences of the studied optical characteristics has been analyzed. The feasibility of using dumbbell-shaped nanoparticles with small aspect ratios in nanomedicine and as optical high-Q resonators has been shown. |
