Broadband quasi perfect absorption using chirped multi-layer porous materials
Noé Jiménez, Vicent Romero-García, Alejandro Cebrecos +3
This work theoretically analyzes the sound absorption properties of a chirped multi-layer porous material including transmission, in particular showing the broadband unidirectional…
Quasi-perfect absorption by sub-wavelength acoustic panels in transmission using accumulation of resonances due to slow sound
Noé Jiménez, Vicent Romero-García, Vincent Pagneux +1
We theoretically and experimentally report sub-wavelength resonant panels for low-frequency quasi-perfect sound absorption including transmission by using the accumulation of cavit…
Ultra-thin metamaterial for perfect and omnidirectional sound absorption
Noé Jiménez, Weichun Huang, Vicent Romero-García +2
Using the concepts of slow sound and of critical coupling, an ultra-thin acoustic metamaterial panel for perfect and omnidirectional absorption is theoretically and experimentally…
