In article number 1900792, Tie Jun Cui, Zhangjie Luo, and co‐workers report their recent progress on a novel intensity‐dependent metasurface with digitally reconfigurable distribution of nonlinearity, extending the concept of digital coding metamaterial to the nonlinear community. Based on an active nonlinear mechanism, the electromagnetic property of the meta‐atom is determined by both incoming intensities and digital signals, which leads to anomalous scattering performances of the metasurface, featuring intensity‐dependent beam deflections pointing to digitally defined orientations. Details about the design, simulations, measurements, and promising applications are presented in the paper.
