Figure | Movable-type reconfigurable metasurface for multiple EM functions. a Mold-inspired meta-atoms from eight categories. b Schematic illustration of the proposed 3-bit movable-type coding metasurface. c Multiple functions enabled by the proposed movable-type coding metasurface, including an MT-RDNN for EM computing, EM holography and contactless human vital sign sensing. MT-RDNN consists of one input layer, three movable-type coding metasurface layers, and one output layer.
