...Saeed Althamer This article explores an innovative vibration suppression design, termed octuple-action (OA), for acoustic metamaterial plates, aimed at mitigating the propagation of acoustic waves. The design's goal is to create broad frequency stopbands, which can be configured by adjusting...

...) are in accord with experimental data. The design of a negative modulus metamaterial at an expected frequency is simple, and the proposed method is expected to provide a basis for the simultaneous control of acoustic metamaterials (AMs) through a variety of methods. acoustic metamaterial split hollow...
