Acoustic Functional Materials Laboratory
The laboratory focuses on physical acoustics, acoustic materials, and intelligent acoustics. We investigate the fundamental principles governing interactions between sound waves and engineered functional materials, and develop new approaches to acoustic functional material design, device fabrication, and intelligent sound-field control. Our research spans fundamental theory, key technologies, and engineering applications to address sound-field control needs in major engineering systems and equipment.
🌀 Research Areas
1. Acoustic Functional Materials for Exotic Wave-Field Control
We study how artificial structures and functional materials shape acoustic fields in complex media, with an emphasis on wave propagation, interference, localization, wavefront shaping, resonant coupling, and nonreciprocal transport. We aim to clarify sound-matter interactions and establish design principles for precise acoustic energy control and advanced acoustic devices.
2. Applications of Acoustic Functional Materials
We develop acoustic functional materials for noise control and acoustic performance optimization in major engineering systems. We focus on high-performance sound-absorbing metamaterials and multifunctional composites based on deep-subwavelength structures, with particular attention to resonance, coupling, interference, and dissipation. We aim to enable broadband, efficient, lightweight, and programmable solutions for sound absorption and insulation in transportation, aerospace, and precision acoustic engineering.
3. Non-Hermitian and Topological Acoustics
We explore the intersection of non-Hermitian physics and topological acoustics, focusing on acoustic implementations of gain/loss modulation, exceptional points (EPs), and topological edge states. We investigate nonreciprocal sound propagation, asymmetric mode coupling, and robust energy transport, with the broader aim of advancing acoustic communication, reconfigurable wave control, and intelligent acoustic systems.
