Mechanical metamaterials are man-made composite structures or materials constructed
from artificial microstructural units with extraordinary static/dynamic properties not found in …

Acoustic/elastic metamaterials exhibit a wealth of unusual properties conducive to wave
manipulation. This review outlines state-of-the-art developments from FPUT chains, granular …

We combine numerical simulations and experiments to design a new class of reconfigurable
waveguides based on three-dimensional origami-inspired metamaterials. Our strategy …

力学超材料是一类由人工微结构单元构筑的复合结构或复合材料, 具有天然材料所不具备的静
力学/动力学性能. 由于这些超常特性通常取决于微结构单元而非材料组分 …

We propose a strategy for constructing an asymmetric sound absorber by coupling two
mutually tuned dark and bright modes. The subsequent requirement is that the dark mode …

We investigate sound propagation in lossy, locally resonant periodic structures by studying
an air-filled tube periodically loaded with Helmholtz resonators and taking into account the …

One-dimensional acoustic waveguide containing subwavelength-sized Helmholtz
resonators is known to exhibit novel physical phenomena. However, no systematic …

With the advance of the research on acoustic metamaterials, the limits of passive
metamaterials have been observed, which prompts the studies concerning actively tunable …

Since its first demonstration of an acoustic metamaterial in the early 21st century, it is widely
used for sound wave manipulation purposes in many applications such as aerospace …

Acoustic metamaterials achieve the function of absorbing sound through equivalent
negative parameters and bandgaps. Sound absorption is closely related to structural design …
