Planar Metamaterial with Toroidal Moment
Yuancheng Fan, Zeyong Wei, Hongqiang Li +2
We observe toroidal response from a planar metamaterial comprised of asymmetric split ring resonators (ASRRs). It is showed that a toroidal-molecule can be constructed through rati…

Low-threshold directional plasmon lasing assisted by spatially coherent surface plasmon polaritons
Yang Cao, Zeyong Wei, Wei Li +5
We theoretically propose directional, low-threshold plasmon lasing in both the near-infrared and visible wavelengths by utilizing spatially coherent surface plasmon polaritons on a…

Negative and Positive Lateral Shift of a Light Beam Reflected from a Grounded Slab
Li-Gang Wang, Hong Chen, Nian-Hua Liu +1
We consider the lateral shift of a light beam reflecting from a dielectric slab backed by a metal. It is found that the lateral shift of the reflected beam can be negative while th…
