Unidirectional scattering induced by the toroidal dipole moment in the system of plasmonic nanoparticles
Lixin Ge, Liang Liu, Shiwei Dai +4
Unidirectional backward and forward scattering of electromagnetic waves by nanoparticles are usually interpreted as the interference of conventional multipole moments (i.e., electr…

A Generic Minimal Discrete Model for Toroidal Moments and Its Experimental Realization
Hong Xiang, Lixin Ge, Liang Liu +4
It is well known that a closed loop of magnetic dipoles can give rise to the rather elusive toroidal moment. However, artificial structures required to generate the necessary magne…
