In article number 1800031 , Din Ping Tsai and co‐workers incorporated integrated‐resonant units (IRUs) into metasurfaces to demonstrate achromatic beam deflectors, achromatic metalenses, and highly efficient versatile polarization convertors operated in the continuous visible‐light range. IRUs are considered as one building block consisting of multiple resonant elements or one resonator supporting multiple modes. Such integrated resonant configurations show a great capacity for achieving a controllable smooth and linear phase dispersion, as well as enhancing working efficiency over a continuous and broad bandwidth, which opens a new avenue for the development of full‐color imaging, display and detection meta‐devices.
