Acoustic metamaterials based on out‐of‐plane actuation can flexibly reconfigure arrayed
unit cells on demand, to shape sound fields for applications such as beam formation or …

Acoustic metasurfaces have shown indispensable abilities for wave control with
subwavelength resolution and enabled exotic sound functions unavailable using naturally …

In recent years, planar aperture‐based acoustic devices have been investigated due to their
thin form factor, high effective transmission, and sound modulation capability. Moreover …

The challenge in reconfigurable manipulation of sound waves using metasurfaces lies in
achieving precise control over acoustic behavior while developing efficient and practical …

Acoustic metamaterials (AMM) are poised to revolutionise the way we control sound and
communicate with our environment. Fundamental theoretical principles surrounding AMMs …

A customized metamaterial tailored for a specific functionality holds significant appeal in
practical applications, yet its alteration after the structure is established can be challenging …

In this thesis, I showcase the effectiveness of acoustic metasurface (AM) based spatial
sound modulators (SSMs) for reconfigurable, cost-effective manipulation of acoustic …
