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

Mechanical metamaterials, also known as architected materials, are rationally designed
composites, aiming at elastic behaviors and effective mechanical properties beyond ('meta') …

Achieving vibration and/or wave attenuation with locally resonant metamaterials has
attracted a great deal of attention due to their frequency dependent negative effective mass …

The ability to control elastic wave propagation at a deep subwavelength scale makes locally
resonant elastic metamaterials very relevant. A number of abilities have been demonstrated …

This paper studies sound transmission loss (STL) of a metamaterial thin plate consisting of
periodic subwavelength arrays of shunted piezoelectric patches bonded to the two surfaces …

Different from the common tunable elastic metasurface (TEM), like piezoelectric active
metasurface, in this paper, we propose a TEM composed of impedance-adjustable subunits …

One dimensional active metamaterials with broadband controllable bending stiffness are
studied in this paper. The key unit of the active metamaterials is composed of a host beam …

A great deal of research has been devoted to controlling the dynamic behaviors of phononic
crystals and metamaterials by directly tuning the frequency regions and/or widths of their …

Increasing sensitivity and signal to noise ratios of conventional wave sensors is an
interesting topic in structural health monitoring, medical imaging, aerospace and nuclear …

The topology concept in the condensed physics and acoustics is introduced into the elastic
wave metamaterial plate, which can show the topological property of the flexural wave. The …
