Metamaterials are artificial materials designed to exhibit effective material parameters that
go beyond those found in nature. Composed of unit cells with rich designability that are …

In the past decades, many mechanical metamaterials with uncommon static properties have
been reported. On the other hand, mechanical metamaterials possessing extraordinary …

From ultrasensitive detectors of fundamental forces to quantum networks and sensors,
mechanical resonators are enabling next‐generation technologies to operate in room …

Vibration suppression at subwavelength scales is of great interest in acoustic and/or elastic
metamaterial engineering which has a wide range of potential applications requiring …

Neurons exhibit excellent signal transmission capacity, which inspire artificial neuron
materials for applications in the field of wearable electronics and soft robotics. In addition …

Attenuating low-frequency sound remains a challenge, despite many advances in this field.
Recently-developed acoustic metamaterials are characterized by unusual wave …

The sound is the pressure disturbance created over air particles above and below
atmospheric pressure. It is a mechanical wave which requires a medium to propagate. The …

Acoustic metasurfaces (AMs) used for reflected sound wavefront manipulation are generally
designed based on the generalized Snell's law (GSL) at a single frequency, suffering from …

After recalling the first Brillouin zone (BZ) and the first irreducible Brillouin zone (IBZ) of a
lattice in terms of its plane crystallographic group, we investigate the danger of restricting a …

Wide band gaps with the propagation of elastic waves at low-frequency are desirable for
phononic crystals in many traditional and novel applications. Inspired by the natural helix …
