    • 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 ...

    • Broadband quarter-wave plate based on dielectricembedded plasmonic metasurface 

      Owiti, Edgar O.; Yang, Hanning; Ominde, Calvine F; Sun, Xiudong (Royal Society of Chemistry, 2017)
      High transmission plasmonic and all-dielectric metasurface wave plates have been reported in recent studies. However, narrow bandwidth and low polarization conversion need to be addressed to attain even better operation ...

    • 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 converter with controllable birefringence based on hybrid all-dielectric-graphene metasurface 

      Owiti, Edgar O.; Yang, Hanning; Liu, Peng; Ominde, Calvine F; Sun, Xiudong (Springer US, 2018-12)
      Previous studies on hybrid dielectric-graphene metasurfaces have been used to implement induced transparency devices, while exhibiting high Q-factors based on trapped magnetic resonances. Typically, the transparency windows ...

    • 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 ...
