Q-factor and absorption enhancement for plasmonic anisotropic nanoparticles
Wei Liu, Bing Lei, Andrey E. Miroshnichenko
We investigate the scattering and absorption properties of anisotropic metal-dielectric core-shell nanoparticles. It is revealed that the radially anisotropic dielectric layer can…
Unidirectional superscattering by multilayered cavities of effective radial anisotropy
Wei Liu, Bing Lei, Jianhua Shi +1
We achieve unidirectional forward superscattering by multilayered spherical cavities which are effectively radially anisotropic. It is demonstrated that, relying on the large effec…
Elusive pure anapole excitation in homogenous spherical nanoparticles with radial anisotropy
Wei Liu, Bing Lei, Jianhua Shi +2
For homogenous isotropic dielectric nanospheres with incident plane waves, Cartesian electric and toroidal dipoles can be tunned to cancel each other in terms of far-field scatteri…
Efficient excitation and tuning of toroidal dipoles within individual homogenous nanoparticles
Wei Liu, Jianhua Shi, Bing Lei +2
We revisit the fundamental topic of light scattering by single homogenous nanoparticles from the new perspective of excitation and manipulation of toroidal dipoles. It is revealed…
Invisible nanowires with interfering electric and toroidal dipoles
Wei Liu, Jianfa Zhang, Bing Lei +2
By studying the scattering of normally incident planewaves by a single nanowire, we reveal the indispensable role of toroidal multipole excitation in multipole expansions of radiat…
Ultra-directional forward scattering by individual core-shell nanoparticles
Wei Liu, Jianfa Zhang, Bing Lei +3
We study the angular scattering properties of individual core-shell nanoparticles that support simultaneously both electric and optically-induced magnetic resonances of different o…
