The emergence of low-frequency dual Fano resonances in chiral twisting metamaterials
Brahim Lemkalli, Muamer Kadic, Youssef El Badri +3
In the current work, through a finite element analysis, we demonstrate that a configuration of chiral cells having syndiotactic symmetry provides dual Fano resonances at low freque…
Longitudinal-Twist Wave Converter based on Chiral Metamaterials
Brahim Lemkalli, Muamer Kadic, Youssef El Badri +3
Advances in material architectures have enabled endowing materials with exotic attributes not commonly available in the conventional realm of mechanical engineering. Twisting, a me…
Tailored Topological Edge Waves via Chiral Hierarchical Metamaterials
Jacopo M. De Ponti, Luca Iorio, Gregory J. Chaplain +3
Precise manipulation of the direction and re-direction of vibrational wave energy is a key demand in wave physics and engineering. We consider the paradigm of a finite frame-like s…
Dynamic cloaking of a diamond-shaped hole in elastic plate
Kun Tang, Eitam Luz, David Amram +3
Invisibility cloaks for flexural waves have been mostly examined in the continuous-wave regime, while invisibility is likely to deteriorate for short pulses. Here, we propose the p…
Mapping of Elastic Properties of Twisting Metamaterials onto Micropolar Continuum using Static Calculations
Brahim Lemkalli, Muamer Kadic, Youssef El Badri +3
Recent developments in the engineering of metamaterials have brought forth a myriad of mesmerizing mechanical properties that do not exist in ordinary solids. Among these, twisting…
Two-scale cut-and-projection convergence for quasiperiodic monotone operators
Niklas Wellander, Sebastien Guenneau, Elena Cherkaev
Averaging certain class of quasiperiodic monotone operators can be simplified to the periodic homogenization setting by mapping the original quasiperiodic structure onto a periodic…
