W-shaped Broadband Attenuation of Longitudinal Waves through Composite Elastic Metamaterial
B. Lemkalli, K. K. Dudek, M. Kadic +4
We investigate a composite elastic meta-slab with exceptional transmission properties, particularly the presence of a W-shaped bandgap. A comprehensive study, utilizing experimenta…
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),…
