Metamaterials enable the modulation of elastic waves or acoustic in unprecedented ways and have a wide range potential applications. This paper achieves simultaneous manipulation surface (SEWs) (SAWs) using two-dimensional acousto-elastic metamaterials (AEMMs). The proposed AEMMs are composed periodic hollow cylinders on semi-infinite substrate. band diagrams frequency responses numerically calculated through finite element approach. exhibit bandgaps for SEWs SAWs, which can also be effectively tuned by modification AEMM geometry. Furthermore, we construct waveguide introduction line defect hence demonstrate its ability to guide SAWs simultaneously. We expect that will contribute development multi-functional wave devices, such as filters dual microelectronics liquid sensors detect more than one physical property.
