An auxetic metamaterial consisting of a re-entrant honeycomb structure with hierarchical
characteristics (RHS-H) is proposed. The new structure is constructed by attaching small re …

A metamaterial of particular interest for underwater applications is the three-dimensional
(3D) anisotropic pentamode (PM), ie, a structure designed to support a single longitudinal …

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

In this work, a method for inverse design of two-dimensional honeycomb pentamode
metastructures (HPM) based on the Conditional Variational Auto-Encoder (CVAE) is …

In this paper we report the numerical design and experimental validation of a pentamode
cloak for scattering reduction of elliptical targets in underwater acoustics. Despite being a …

Sound diffusion performance is considered as an important issue in building acoustics. A
well-diffused sound field can effectively enhance the human listening experience. In this …

We develop an optimization framework for the design of acoustic cloaks, with the aim of
overcoming the limitations of usual transformation-based cloaks in terms of microstructure …

Compared to acoustic cloak, elastic wave cloak is difficult to construct due to inapplicability
of form invariance for the control equations. Traditional elastic wave cloak is limited to Willis …

Pentamode metamaterial (PM) has enormous application potential in the design of
lightweight bodies with superior vibration and noise-reduction performance. To offer …

The recent progress in the context of elastic metamaterials and modulated waveguides with
digitally controllable properties has opened new pathways to overcome the limitations …
