Controlling sound with acoustic metamaterials
Acoustic metamaterials can manipulate and control sound waves in ways that are not
possible in conventional materials. Metamaterials with zero, or even negative, refractive …

Elastic metamaterials with local resonances: an overview
Metamaterials are artificial composite materials engineered to have properties that may not
be found in nature. By exploring locally resonant effect of the building units, elastic …

An elasto-mechanical unfeelability cloak made of pentamode metamaterials
Metamaterial-based cloaks make objects different from their surrounding appear just like
their surrounding. To date, cloaking has been demonstrated experimentally in many fields of …

Invisible sensor: simultaneous sensing and camouflaging in multiphysical fields
TZ Yang, X Bai, D Gao, L Wu, B Li, JTL Thong… - ar** force of acoustical Bessel beams on a sphere and stable tractor beams
We seek stable tractor beams that not only axially pull objects but also transversely trap the
object. Transverse force acting on a spherical particle centered on the axis of acoustic …

Boundary and interface conditions in the relaxed micromorphic model: Exploring finite-size metastructures for elastic wave control
In this paper, we establish well-posed boundary and interface conditions for the relaxed
micromorphic model that are able to unveil the scattering response of fully finite-size …

Cancellation of acoustic scattering from an elastic sphere
Recent research has suggested the possibility of creating acoustic cloaks using
metamaterial layers to eliminate the acoustic field scattered from an elastic object. This …
