Nonreciprocal topological kink-wave propagation in mechanical metamaterials
Brahim Lemkalli, Qingxiang Ji, Jingyi Zhang +3
Nonlinear mechanical metamaterials can exhibit emergent transport phenomena that mimic topological protection without relying on linear band topology. Here, we realize a bifurcatio…
Clay metaBrick-based motif to enhance thermal and acoustic insulation
Brahim Lemkalli, Saad Bensallam, Muamer Kadic +4
Acoustic metamaterials have gained popularity as promising materials for enhancing noise reduction. Here, we explore the use of metamaterials, based on Helmholtz resonators (HRs),…
Pumping with Symmetry
Julio Andrés Iglesias Martínez, Muamer Kadic, Vincent Laude +1
Re-configurable materials and meta-materials can jump between space symmetry classes during their deformations. Here, we introduce the concept of singular symmetry enhancement, whi…
Micro-scale Mechanical Metamaterial with a Controllable Transition in the Poisson's Ratio and Band Gap Formation
K. K. Dudek, J. A. Iglesias Martínez, G. Ulliac +4
The ability to change significantly mechanical and wave propagation properties of a structure without rebuilding it has been one of the main challenges in the field of mechanical m…
Elastic Wave Near-Cloaking
Davide Enrico Quadrelli, Richard Craster, Muamer Kadic +1
Cloaking elastic waves has, in contrast to the cloaking of electromagnetic waves, remained a fundamental challenge: the latter successfully uses the invariance of Maxwell's equatio…
Chiral Triclinic Metamaterial Crystals Supporting Isotropic Acoustical Activity and Isotropic Chiral Phonons
Yi Chen, Muamer Kadic, Martin Wegener
Recent work predicted the existence of isotropic chiral phonon dispersion relations of the lowest bands connected to isotropic acoustical activity in cubic crystalline approximants…
