Manipulating circularly‐polarized waves in desired multi‐prescribed manners, especially in both transmission and reflection schemes, is of particular importance. In the article number 1700321, the authors propose a general strategy by using specially tailored Pancharatnam‐Berry meta‐atoms with helicity‐dependent transmissions and reflections to design high‐efficiency CP bifunctional metasurfaces. As a proof, two bifunctional metadevices are designed and characterized at microwave frequencies, and both of them exhibit very high efficiencies (88%‐94%).
