Electroacoustic Metamaterials

This lecture explores the development of electroacoustic metamaterials and metasurfaces, focusing on the concept of Electroacoustic Resonators. It covers the principles, properties, and applications of these materials in noise control strategies, sound absorption, and room acoustics. The presentation delves into the design and implementation of composite right/left-handed acoustic metamaterials, as well as the use of active metasurfaces for controlling sound reflection and transmission. The lecture also discusses the challenges and potential of achieving constant amplitude waveguides and the utilization of electroacoustic resonators for achieving desired sound field control.
