Acoustic metamaterials provide a powerful tool for designing effective noise-reducing means
at subwavelength scales. This paper is concerned with the sound insulation characteristics …

How to endow diverse functions for lightweight structures without increasing mass has
always been a major challenge (eg, to have simultaneous high static stiffness and extreme …

We propose an acoustic-mechanical metasurface with simultaneous sound absorption and
vibration reduction functionalities. This acoustic-mechanical feature results from a nonlocal …

We propose a contactless and non-closed strategy to mitigate the sound radiated from an
underwater source. The problem is formulated as the interaction of the source with different …

Owing to the instinct difference in atomic buildings between solid and liquid, the phase
change of material can fundamentally change wave energy propagation. In the present …

To address the issue of low-frequency noise control in helicopter cabins below 500 Hz, a
design paradigm of acoustic metamaterials is introduced for the acoustic treatment of the …

Achieving mass manufacturability and convenient deployability is the cornerstone to enable
the widespread adoption of acoustic metamaterials. This work is poised to address the …
