The authors study the propagation of Lamb waves in two-dimensional locally resonant
phononic-crystal plates, composed of periodic soft rubber fillers in epoxy host with a finite …

The field of engineered materials with designed properties is expected to continue to grow in
the future, and metamaterials are instrumental in allowing this freedom of design …

In this paper, we numerically and experimentally study the waveguiding of Lamb modes in a
thin plate with a periodic stubbed surface and propose a frequency-selection method based …

In this letter, we numerically demonstrate focusing of the lowest antisymmetric Lamb wave in
a gradient-index phononic crystal (PC) silicon plate and its application as a beam-width …

低频机械波在传播过程中穿透力强, 难以衰减, 特别是次声频段的机械波易与机体器官发生共振,
对身体造成危害. 为了实现对低频机械波的有效控制, 解决现代工业生产和生活中普遍存在的 …

A new design for locally resonant metamaterial sandwich plates is proposed in this paper for
noise insulation engineering applications. A systematic method to tune the resonance …

In recent years, advances in timber engineering, combined with an associated evolution in
building codes, have led to a significant expansion of multi-storey timber construction …

Double panel partitions with a foam core suffer a poor sound transmission loss at their mass-
spring-mass resonance frequency. This paper considers the use of vibro-acoustic resonant …

Lattice structures have long fascinated physicists and engineers not only because of their
outstanding functionalities, but also for their ability to control the propagation of elastic …
