Acoustic metamaterials and metasurfaces are artificial structures designed to control, direct, and manipulate sound waves or phonons in gases, liquids, and solids, offering unprecedented capabilities for shaping acoustic wave behavior. As a specialized branch within the broader field of metamaterials, the development of acoustic metamaterials has both drawn from and influenced advancements in electromagnetic metamaterials, creating a mutually beneficial relationship between the two fields.
This session focuses on exploring recent progress in acoustic metamaterials and metasurfaces, covering fundamental principles, numerical schemes, innovative design models, experimental demonstrations and a variety of practical applications like acoustic absorption and noise control.
