Greater demands for underwater sound absorption materials have been growing due to the
concern about underwater noise control in water. Among the range of existing materials …

Perhaps the most familiar concepts when discussing acoustic scattering by bubbles are the
resonance frequency for bubble pulsation, the bubbles' damping, and their scattering and …

In order to study and further develop underwater acoustic absorption structures, we present
an underwater metamaterial for broadband acoustic absorption in this study, which is …

The problem of attenuation and sound speed of bubbly media has remained partially
unsolved. Comprehensive data regarding pressure-dependent changes of the attenuation …

A bubble metascreen, ie, a single layer of gas inclusions in a soft solid, can be modeled as
an acoustic open resonator, whose behavior is well captured by a simple analytical …

Soft acoustic metamaterials that embed soft materials in a host media have promising
applications in aqueous environments. However, the preparation of soft metamaterials …

The fields of photonics and phononics encompass the fundamental science of light and
sound propagation and interactions in complex structures, as well as its technological …

We demonstrate the experimental realization of a multiresonant metamaterial for Lamb
waves, ie, elastic waves propagating in plates. The metamaterial effect comes from the …

The anechoic coating capable of absorbing sound energy in low frequency and broadband
is essential to conceal underwater vehicles. In this work, metagrating has been …

An approximate analytical model is presented to investigate sound transmission, reflection
and absorption of a rubber-like medium comprising a single layer of periodic cylindrical …
