Coherent control of metagratings through multiple wave excitations provides new opportunities for highly reconfigurable broadband metasurfaces with large diffraction efficiency, beyond the limitations of conventional approaches. In article number 2002341, Ming Kang, Xueqian Zhang, Alex Krasnok, Jiaguang Han, Andrea Alù, and co‐workers discover that energy distribution between the diffraction orders can be continuously controlled on‐demand by simply changing the relative phase difference between two excitation signals.
