New Frontiers in Acoustic and Elastic Metamaterials and Metasurfaces

In the past two decades, the field of acoustic and elastic metamaterials has witnessed significant advancements. Innovations include extreme elastic parameters, invisible cloak, non-reciprocal propagation, and interdisciplinary research in physics, materials, and engineering. Metasurfaces uniquely provide nonlinear wave responses.

This special topic aims to present the latest developments in science and engineering pertaining to acoustic and elastic metamaterials and metasurfaces, focusing on exploring cutting-edge directions such as space-time modulation, non-Hermitian design, topological design, and advanced engineering applications including multi-functional and reconfigurable designs.
