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 ... -
Polarization Converter with Controllable Birefringence Based on Hybrid All-Dielectric-Graphene Metasurface
Owiti, Edgar O; Yang, Hanning; Liu, Peng; Ominde, Calvine F (Nanoscale Research Letters, 2018)Previous studies on hybriddielectric-graphenemetasurfaceshavebeenusedtoimplementinducedtransparency devices,while exhibiting high Q-factors based on trapped magnetic resonances.Typically,the transparencywindows are ...
