In the past two decades, the research on acoustic metamaterials has flourished, which is
also benefited from the development of additive manufacturing technology. The exotic …

The study of phononic materials and structures is an emerging discipline that lies at the
crossroads of vibration and acoustics engineering and condensed matter physics. Broadly …

This Colloquium presents an overview of the research on nonlinear electromagnetic
metamaterials. The developed theoretical approaches and experimental designs are …

Phononic materials are periodically arranged building blocks in the form of material
properties, geometries, and/or boundary conditions. This synthetic architecture makes …

In this paper we review recent progress on the analysis, experimental exploration, and
application of elastic wave propagation in weakly nonlinear media and metamaterials. We …

Although elastic metamaterials in a subwavelength scale can control macroscopic waves, it
is still a big challenge to attenuate elastic waves at very low frequency (a few tens Hz). The …

Wave propagation in metamaterial honeycombs endowed with periodically distributed
nonlinear resonators is addressed. The linear and nonlinear dispersion properties of the …

In this paper, we report a new type of bandgap phenomenon called “amplitude-induced
bandgap”, which is induced by amplitude in nonlinear metamaterials. Generally, bandgap …

The powerful energy carried by low-frequency vibration is often challenging to be effectively
attenuated using traditional dam** materials. If low-frequency vibration can be controlled …

The propagation of waves in nonlinear acoustic metamaterial (NAM) is fundamentally
different from that in conventional linear ones. In this article we consider two one …
