(a) Schematic of the Timoshenko-Ehrenfest beam-based reconfigurable elastic metasurface (TREM) for multifunctional wave manipulation (whole reflection, self-acceleration, wave focusing, and anomalous refraction). (b) Picture of the substrate for the (c) meeting parts designed primarily based on the Timoshenko-Ehrenfest beam concept. (d) The assembled TREM on the substrate plate, with every part configured to manage the
