This broad review summarizes recent advances and “hot” research topics in nanophononics
and elastic, acoustic, and mechanical metamaterials based on results presented by the …

Metasurfaces, ultrathin metamaterials constructed by planar meta-atoms with tailored
electromagnetic (EM) responses, have attracted tremendous attention due to their exotic …

Noise pollution impacts the well-being of millions of people on a daily basis and can lead to
serious health issues such as hearing loss and stress. Develo** efficient yet cost-effective …

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

The introduction of engineered resonance phenomena on surfaces has opened a new
frontier in surface science and technology. Pillared phononic crystals, metamaterials, and …

Acoustic metamaterials (AMs), which are materials composed of subwavelength periodic
artificial structures with specific designs, have drawn significant research attention. This is …

The valley degree of freedom in crystals offers great potential for manipulating classical
waves, however, few studies have investigated valley states with complex wavenumbers …

Introducing a negative-stiffness mechanism (NSM) into a traditional linear resonator to form
a high-static-low-dynamic-stiffness (HSLDS) resonator is an ideal way to create a low …

We theoretically and experimentally investigate a helical acoustic metasurface capable of
providing a modulated sound-reflected wavefront and a continuously tunable broadband …

In this contribution, a review study is established in order to gather, classify and organize all
of the previous researches on the sound insulation characteristics of plate structures with …
