Modulational instability of a recent nonlinear plasmonic metamaterial: Finite-difference-time-domain simulations
Yi S. Ding, Jiasen Zhang, Ruo-Peng Wang
By doing time-domain simulations, we find the proposal for negative-to-positive index switching proposed in [Physical Review Letters, 106 105503 (2012)] may be fragile. The negativ…

Plasmonic Demultiplexer and Guiding
Chenglong Zhao, Jiasen Zhang
Two-dimensional plasmonic demultiplexers for surface plasmon polaritons (SPPs), which consist of concentric grooves on a gold film, are proposed and experimentally demonstrated to…

The extraordinary radiation pattern of an optical rod antenna
Chenglong Zhao, Jiasen Zhang
We investigated the radiation pattern of an optical rod antenna and found that it had many features compared with its conventional radio-wave equivalents. After defining a paramete…
