Q-factor and absorption enhancement for plasmonic anisotropic nanoparticles

Liu, Wei; Lei, Bing; Miroshnichenko, Andrey E


We investigate the scattering and absorption properties of anisotropic metal-dielectric core-shell nanoparticles. It is revealed that the radially anisotropic dielectric layer can accelerate the evanescent decay of the localized resonant surface modes, leading to Q-factor and absorption rate enhancement. Moreover, the absorption cross section can be maximized to reach the single resonance absorption limit. We further show that such artificial anisotropic cladding materials can be realized by...[Show more]
