Urban trees are often planted in a periodic arrangement in space. This study takes urban
trees as natural metamaterials. Based on the metamaterial theorem, a three-dimensional …

Motivated by the importance of lattice structures in multiple fields, we numerically investigate
the propagation of flexural waves in a thin reticulated plate augmented with two classes of …

Forest trees have been shown to act as a natural metamaterial to attenuate elastic waves.
However, the existing studies assumed that forest trees are located on homogeneous soils …

Inspired by sonic engineering, locally resonant metamaterials have attracted much attention
from researchers in civil engineering for their unique characteristics of stress wave …

The development of seismic metamaterials has attracted much research interest in the past
decade. Efforts have been made by using experimental and theoretical approaches to …

Composite materials with engineered band gaps are promising solutions for wave control
and vibration mitigation at various frequency scales. Despite recent advances in the design …

In this paper, the physics of horizontally polarized shear waves traveling across a locally
resonant metasurface in an unconsolidated granular medium is experimentally and …

The application of metamaterial in civil engineering to achieve isolation of a building by
controlling the propagation of seismic waves is a substantial challenge because seismic …

Explicit asymptotic formulations are derived for Rayleigh and Rayleigh-type interfacial and
edge waves. The hyperbolic–elliptic duality of surface and interfacial waves is established …

The article analyses two potential metamaterial designs, the metafoundation and the
metabarrier, capable to attenuate seismic waves impact on buildings or structural …
