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

Mechanical metamaterials exhibit some superior mechanical properties such as ultrahigh
strength-to-weight ratio, negative bulk-modulus, negative stiffness, negative mass-density …

Metamaterials are man-made substances with unique spatial alternations in their constituent
components. They are widely used in modifying elastic, acoustic, or electromagnetic …

We investigate theoretically the band structure of flexural waves propagating in an elastic
metamaterial thin plate. Kirchhoff-Love thin plate theory is considered. We study the …

This study presents a strategy of vibration suppression of a beam when multiple resonant
frequencies of the structure are excited. The methodology operates on the ability of local …

According to the mass law, a dense and thick soundproofing material is generally used to
block low-frequency sounds. However, lightweight thin soundproofing materials in the form …

We explore a phononic crystal Luneburg lens through design, fabrication, and analysis for
omnidirectional elastic wave focusing and enhanced energy harvesting both numerically …

Enhancing vibration isolation with local resonance metamaterials has attracted widespread
attention due to the low-frequency band gap. However, the narrow band gaps limit its …

We investigate the complex band structure and forced response of flexural waves
propagating in an elastic metamaterial thick plate. Mindlin-Reissner thick plate theory is …

Thermally tunable elastic wave transport with controllable topological properties in a thin
plate is investigated. For the prior plate-type phononic crystals designed with passive …
