Bi-functional metamaterial based on Helmholtz resonators for sound and heat insulation
Brahim Lemkalli, Zine El Abiddine Fellah, Sébastien Guenneau +3
Over the last few decades, both heat and broadband sound reduction have become increasingly significant as a result of concerns about the environment and noise pollution. In order…
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),…
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…
