Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far
beyond those found in nature, through artificial design of the topology or ordered structure of …

Acoustic metamaterials, structured to produce anomalous reflection and refraction indices
that are not found in conventional materials, are gaining prominence in engineering …

The effective operation of certain electronic, medical, industrial, and testing equipment relies
on high-quality focusing and imaging capability, which also plays a vital role in the field of …

Acoustic metasurfaces are at the frontier of acoustic functional material research owing to
their advanced capabilities of wave manipulation at an acoustically vanishing size. Despite …

Acoustic metasurfaces have enabled unprecedented control over acoustic waves, offering
opportunities in areas such as holographic rendering, sound absorption, and acoustic …

Conventional sound barriers impede airflow at the same time. Recent advances in acoustic
metasurfaces provide a solution for air-permeable barriers utilizing the Fano-like …

A severe limitation of current acoustic metasurfaces remains in their modest tunability to
meet multifrequency requirements and alterable functionalities on demand. Here, a …

A thin metasurface has shown powerful capabilities in controlling either incident
electromagnetic (EM) waves or radiation waves, but is difficult for both. Here, a self‐feeding …

In this study, we introduce a novel perforated Miura-ori phononic structure (PMPS) and
investigate the tunability of complete bandgaps or partial bandgaps in specific directions …
