A new publication from Opto-Electronic Advances; DOI 10.29026/oes.2022.210014 overviews terahertz metasurface zone plates with arbitrary polarizations to a fixed polarization conversion. As an ...

Fig. 1. (a) THz optical path diagram based on metasurface. By controlling the phase delays of LCP and RCP waves by unit cells, metasurface can transmit the LCP and RCP components of the incident ...
