Mechanical metamaterials at the microscale exhibit exotic static properties owing to their
engineered building blocks,,–, but their dynamic properties have remained substantially less …

Broadband effectiveness and impedance mismatching in fluid-structure coupling remain
significant obstacles in the pursuit of broadband high-efficient high-symmetrical …

The ability to design materials for wave propagation behaviors has high potential for impact
in medical imaging, telecommunications, and signal processing. The dispersion relation is …

The quasi-static properties of micro-architected (meta) materials have been extensively
studied over the past decade, but their dynamic responses, especially in acoustic …

We provide a theoretical framework to mold time-modulated mechanical metamaterials with
frequency conversion and wave-steering capabilities. To illustrate the concept, we initially …

This paper introduces a novel design strategy for phononic crystals (PnCs) that significantly
enhances their wave amplification and focusing capabilities, making them highly suitable for …

We experimentally demonstrate the capability of architected plates, with a frame-like cellular
structure, to inhibit the propagation of elastic flexural waves. By leveraging the octet topology …

Metamaterials with functional responses can exhibit varying properties under different
conditions (eg, wave‐based responses or deformation‐induced property variation). This …

Wave concentrators have important application value in ocean engineering. Moreover, the
performance of a concentrator on structural protection is important in the context of the …

In this work, we present first tests of a new implantable sensor concept based on acoustic
metamaterials and ultrasound interrogation tested with animal tissue. The metamaterial …
