A rapidly expanding area of research in materials science involves the development of
routes to complex 3D structures with feature sizes in the mesoscopic range (that is, between …

The increasing demand for geometrically complex structures—specifically, higher-inlet-
temperature turbine blades for the fifth-generation or other high-generation machines of …

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

Acoustic metamaterials (AMM) and phononic crystals (PC) have the potential to unfold a
new wave of disruptive technologies to radically transform human interactions, sensory …

Soft porous silicone rubbers are demonstrated to exhibit extremely low sound speeds of tens
of m/s for these dense materials, even for low porosities of the order of a few percent. Our …

This paper discusses the formation of soft porous materials obtained by the polymerization
of inverse water-in-silicone (polydimethylsiloxane, PDMS) emulsions. We show that the …

Advanced devices for acoustic negative refraction and cloaking can be achieved by utilizing
acoustic metamaterials. However, the capacities of acoustic metamaterials often are …

We present a multiband double-negative acoustic metamaterial (AM) based on coupled
Helmholtz resonators (HRs). By assembly of the detuned HR pairs with the optimized …

We introduce cubic bubbles that are pinned to 3D printed millimetric frames immersed in
water. Cubic bubbles are more stable over time and space than standard spherical bubbles …

Acoustic metamaterials (AMMs) and acoustic metasurfaces (AMSs) are artificially structured
materials with unique properties not found in natural materials. We review herein the …
