Abstract: According to an embodiment of present disclosure, there is provided a metalens formed with a plurality of meta-atoms on one surface, including: a first co-polarization channel through which left-handed circular polarization (LCP) incident light exits as left-handed circular polarization (LCP) light, a second co-polarization channel through which right-handed circular polarization (RCP) incident light exits as right-handed circular polarization (RCP) light, a first cross-polarization channel through which left-handed circular polarization (LCP) incident light exits as right-handed circular polarization (RCP) light, and a second cross-polarization channel through which right-handed circular polarization (RCP) incident light exits as left-handed circular polarization (LCP) light, wherein first exit light exiting through the first co-polarization channel and the second co-polarization channel, second exit light exiting through the first cross-polarization channel, and third exit light exiting through the second cross-polarization channel are different in optical characteristics.
