Description
Summary:Active Metamaterials In article number 2303541, Ruike Renee Zhao and co‐workers present a novel magneto‐mechanical metamaterial that employs a double‐layer design to change area density while preserving the overall area for good conformability during actuation. Magnetic actuation facilitates rapid and reversible structural deformation between multiple modes. This allows for the metamaterial to control the propagation of in‐plane elastic waves of different frequencies.
