A new design of a space‐time‐coding digital metasurface for high‐efficiency spatial synthesis is proposed by Qiang Cheng, Shi Jin, Tie Jun Cui, and co‐workers, in article number 1900133. By employing linear phase modulation to the metasurface, both frequency conversion and beam shaping are implemented simultaneously with the maximum conversion efficiency of 88.81% and largest harmonic suppression ratio of 21.03dB. The presented work is promising for the next‐generation wireless communication and radar systems.
