Constructing a ocean Internet of Things requires an essential ocean environment monitoring
system. However, the widely distributed existing ocean monitoring sensors make it …

Enhancing vibration isolation with locally resonant metamaterials has attracted wide
attention due to low-frequency band-gap. Moreover, nonlinear periodic structure could …

A new type of the elastic metamaterial beam with X-shaped local resonators is designed and
the vibration attenuation property of the proposed structure is investigated by the spectral …

In recent years, the innovative design of metamaterials and the study of bandgap
characteristics have become the focus of research. The flexible setting of small added mass …

Low-and mid-frequency range vibrations usually present issues in their insulation. The
development of periodic metamaterials (artificially engineered structures) has been …

This study proposes a viscoelastic metamaterial containing negative-stiffness elements,
which exhibits both a dam** enhancement effect and a tunable ultra-low frequency band …

This paper aims to present a theoretical model of flexural wave bandgaps in locally resonant
cylindrical curved shell and investigates a technique for broadband wave mitigation using a …

Unlike conventional metamaterials with a periodic array of identical resonators, rainbow
metamaterials consist of an array of discrete resonators with a spatially varying parameter …

Drawing on the principles of energy convergence and local resonance, the acoustic black
hole (ABH) emerges as a promising unit cell within phononic crystals (PCs). It has the …

Periodic media have been shown to exhibit wave attenuation in frequency ranges called
band gaps. The challenge is designing feasible periodic structures that present total band …
