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),…
