Metamaterials (MMs), which include phononic crystals (PCs) as a particular type, exhibit
anomalous wave propagation properties through artificial design of topologies or lattice …

Willis materials exhibit macroscopic cross-coupling between particle velocity and stress as
well as momentum and strain. However, Willis coupling coefficients designed so far are …

This paper studies the dynamic properties of a 3D chiral mechanical metamaterial, which
largely depend on tacticity describing the connection forms of the chiral unit. Based on the …

Elastic wave propagation characteristics of elastic metamaterial plates embedded scatterer
with various lattices are explored numerically and experimentally in this study, for the …

Aiming to attenuate very low-frequency flexural wave in a thin plate, this paper proposes a
meta-plate model by periodically attaching high-static-low-dynamic-stiffness (HSLDS) …

Dynamic homogenization theories are powerful tools for describing and understanding the
behavior of heterogeneous media such as composites and metamaterials. However, a major …

Locally resonant acoustic metamaterial (LRAM) panels are excellent candidates for the low-
frequency flexural wave attenuation in thin structures. To enable the efficient analysis and …

Recent interest in metamaterials has led to a renewed study of wave mechanics in the
different branches of physics. Elastodynamics involves a special intricacy, owing to the …

In order to achieve low frequency vibration and noise reduction, researchers have found and
explored many types of metamaterial structures. Based on this, an innovative multiphase …

Metamaterials that exhibit a constitutive coupling between their momentum and strain, show
promise in wave manipulation for engineering purposes and are called Willis materials …
