As a subcategory of acoustic metamaterials, membrane acoustic metamaterials (MAMs) are
lighter and more adjustable than other types of acoustic metamaterials when it comes to low …

Advancements in additive manufacturing (AM) technology are promising for the creation of
acoustic materials. Acoustic metamaterials and metasurfaces are of particular interest for the …

The vibroacoustic response of a structurally excited cylindrical shell submerged in water is
presented. The shell is coated with a soft elastic material embedded with circumferential …

A hybrid honeycomb structure (HHS) with energy dissipation enhancement effect is
proposed for broadband underwater sound absorption. The HHS is constructed using …

An automatically adaptive metamaterial sound absorber is designed, which can absorb
tunable low‐frequency (< 500 Hz) sounds under ventilated conditions by designing a …

Metamaterials have offered unprecedented potentials for wave manipulations. However,
their applications in underwater acoustic wave control have remained largely unexplored …

A novel spider-web-like multi-hole variable cross-section phononic crystal (VCSPC) is
proposed in this study, along with a misaligned stacking approach for constructing thin …

A major source of anthropogenic noise pollution in the marine environment is underwater
radiated sound from marine vessels. This thesis investigates sound radiation from a coated …

Acoustic metamaterials (AMMs) are an exciting technology because they are capable of
responding to vibrations in ways that are impossible to achieve with conventional materials …

Over the past few decades, acoustic metamaterials have been demonstrated to achieve a
wide range of applications including sensing, communication, wave engineering, and so on …
