This broad review summarizes recent advances and “hot” research topics in nanophononics
and elastic, acoustic, and mechanical metamaterials based on results presented by the …

The application of smart materials and metastructures has been rapidly increasing in
advanced multiphysical systems because of their ability to modify mechanical responses by …

Realizing a low-frequency and broad bandgap is extremely challenging because the lattice
constant, equivalent stiffness, and equivalent density must be taken into account in practice …

This paper analytically and experimentally investigates the potential of a piezoelectric
metamaterial beam with a spatial grading pattern for broadband vibration attenuation …

Topological boundary states, the smoking gun of topological insulators (TIs), have been
widely investigated in a variety of settings [1, 2]. Among the youngest members of this …

The phenomenon of retroreflection of light characterized by a single transversely polarized
wave has been extensively explored. However, the phenomenon of retroreflection of a …

The dynamics of topological boundary modes in both periodic and quasi-periodic
electromechanical metastructures is investigated, with a focus on their applications to …

Precise manipulation of the direction and redirection of vibrational wave energy is a key
demand in wave physics and engineering. We consider the paradigm of a finite framelike …

This paper is concerned with flexural and torsional waves propagation in locally-resonant
thin-walled beams with open cross section. A beam with monosymmetric cross section …

We investigate robust large-area elastic transverse wave propagation in an actively tunable
membrane-type acoustic metamaterial. The waveguide with multiple degrees of freedom to …
