Effect of symmetry defect on the edge resonance of semi-infinite FGM plates
Shengyu Tang, Wenping Bi, Jingwei Yin +1
The effect of asymmetric functionally graded material on the edge resonance and the Fano resonance in semi-infinite FGM plates are reported in this work. The edge resonance is weak…
Spatial transient behavior in waveguides with lossy impedance boundary conditions
Wei Guo, Juan Liu, Wenping Bi +3
Attenuation in acoustic waveguides with lossy impedance boundary conditions are associated with non-Hermitian and non-normal operators. This subject has been extensively studied in…
Anomalous transmission through periodic resistive sheets
Antonin Coutant, Yves Aurégan, Vincent Pagneux
This work investigates anomalous transmission effects in periodic dissipative media, which is identified as an acoustic analogue of the Borrmann effect. For this, the scattering of…
Slow sound laser in lined flow ducts
Antonin Coutant, Yves Aurégan, Vincent Pagneux
We consider the propagation of sound in a waveguide with an impedance wall. In the low frequency regime, the first effect of the impedance is to decrease the propagation speed of a…
Observation of edge waves in a two-dimensional Su-Schrieffer-Heeger acoustic network
Li-Yang Zheng, Vassos Achilleos, Olivier Richoux +2
In this work, we experimentally report the acoustic realization the two-dimensional (2D) Su-Schrieffer-Heeger (SSH) model in a simple network of air channels. We analytically study…
Rainbow-trapping absorbers: Broadband, perfect and asymmetric sound absorption by subwavelength panels with ventilation
Noé Jiménez, Vicent Romero-García, Vincent Pagneux +1
Perfect, broadband and asymmetric sound absorption is theoretically, numerically and experimentally reported by using subwavelength thickness panels in a transmission problem. The…
