Abstract

Abstract : Driven by system integration and device miniaturization, a single device with multiple functions is desirable. In article number 1900182, Xianzhong Chen, Yiming Zhu, and co‐workers demonstrate a metalens that can focus the incident THz waves into two focal spots with predesigned polarization rotation. This approach not only provides a platform for multiplexing of focusing and polarization rotation, but also opens a novel avenue for polarization‐dependent imaging.
