Conceptual demonstration of MCM. (IMAGE)
Caption
schematic diagram and function illustration of the proposed mcm and its magic cube supercell. MCM is formed by an array of supercells arranged in a square lattice of magic cube as a plinth. The reflective phase responses of each meta-particle are controlled by 3d permutations of sub-blocks directly below it and can be independently tuned over six levels. Under full-polarization incident electromagnetic waves, MCM can be mechanically and flexibly processed to realize customized functionalities, including but not limited to type-Ⅰ (reconfigurable achromatic metalens) and type-Ⅱ (tunable multifunctional beam generators) ranging from f1 to f4. the upper-middle panel exhibits the meta-particle with transparent substrate, allowing for real-time sequence mapping visually.
