Broadband quarter-wave plate based on dielectric-embedded 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 recentstudies. However, narrow bandwidth and low polarization conversion need to be addressed to attaineven better operation ... -
Dual-band graphene-induced plasmonic quarter-wave platemetasurface in the near infrared
Owiti, Edgar; Yang, Hanning; Ominde, Calvine; Sun, Xiudong (Springer Berlin Heidelberg, 2017)Weak graphene plasmon is a key challenge for graphene-based meta surfaces in the visible and near-in-frared regions. In this study, we have numerically designed and demonstrated a tunable, ultra thin, ... -
Polarization independent and tunable plasmoninduced transparency for slow light
Yang, Hanning; Owiti, Edgar O; Yenpo, Pai; Sun, Xiudong (Royal Society of Chemistry, 2017)A novel metamaterial composed of a Ag nanoprism periodic tetramer is proposed in this paper. Themetamaterial has high structural symmetry and shows polarization independent plasmon-inducedtransparency (PIT), demonstrated ...
