A vector beam modulator based on a coding metasurface is presented by Tie Jun Cui and co‐workers in article number 1700548 to encode information on the orthogonal linear polarization bit and orbital angular momentum (OAM) mode bit. Compared with the usual phase coding metasurfaces, the information loss in transmission by this method can be reduced dramatically because of the orthogonality among coded symbols.
