Ag nanoprism metamaterial based tunable plasmonic logic gate
Yang, Hanning; Owiti, Edgar O.; Li, Siren; Pei, Yanbo; Shi, Hongyan; Sun, Xiudong (IOP Publishing, 2017)A metamaterial comprised of asymmetrically arranged Ag nanoprisms has been proposed and investigated in this paper. The metamaterial shows a polarization dependent PIT effect. The metamaterial with its periodic length ... -
Localized Surface Plasmon Resonance Dependence on Misaligned Truncated Ag Nanoprism Dimer
Yang, Hanning; Owiti, Edgar O.; Jiang, Xiangqian; Li, Siren; Liu, Peng; Sun, Xiudong (Springer, 2012)Misaligned edge-to-edge dimers are the common products during the preparation of Ag nanoprism dimers using self-assembly method. However, in the self-assembly method, Ag nanoprisms are easily truncated because they are easy ... -
Polarization independent and tunable plasmon induced transparency for slow light
Yang, Hanning; Owiti, Edgar; Pei, Yanbo; Li, Siren; Liu, Peng; Sun, Xiudong (Royal Society of Chemistry, 2017)A novel metamaterial composed of a Ag nanoprism periodic tetramer is proposed in this paper. The metamaterial has high structural symmetry and shows polarization independent plasmon-induced transparency (PIT), demonstrated ...
