Acoustic metamaterials (AMMs) are a core area of metamaterials research — delivering bespoke wave control – at the forefront of metamaterials commercialisation. AMMs are being implemented noise and vibration harshness control applications and across science and defence sectors with applications in wave filtering, sensing, communications, energy harvesting, thermal emission control, and aeroacoustics.

The landscape of AMM research is continually expanding, incorporating multiple wave regimes and pushing the boundaries of metamaterial physics, offering potential solutions to crucial societal challenges, like noise pollution or sustainability.

The newly published Roadmap for Acoustic Metamaterials captures the state of the field in 2024.
