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 ...

Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...
