Coupled Decorated Membrane Resonators with Large Willis Coupling
Joshua Lau, Suet To Tang, Min Yang +1
We report the experimental studies on an acoustic scatterer consisting of a pair of coupled decorated membrane resonators (DMRs) that exhibits near extreme contrast in reflection a…
Sound Transmission Through a Finite-Sized Double Panel Cavity with a Micro-Perforated Panel Insertion
Zhenwei. Zhou, Jiaming. Wu, Zhiyu Yang
This paper proposes a noise insulation cavity composed of two parallel plates and a micro-perforated plate insertion parallel to the plates, which divides the cavity between the pl…
Super Damping of Mechanical Vibrations
Ka Yan Au Yeung, Brian Yang, Liang Sun +2
We report the phenomenon of coherent super decay, where a linear sum of several damped oscillators can collectively decay much faster than the individual ones in the first stage, f…
High-efficiency Ventilated Metamaterial Absorber at Low Frequency
Xiaoxiao Wu, Ka Yan Au-Yeung, Xin Li +7
We demonstrate a ventilated metamaterial absorber operating at low frequency (< 500 Hz).With only two layers of the absorption units, high-efficiency absorption (> 90%) has been ac…
Wave Manipulations by Coherent Perfect Channeling
Xiaonan Zhang, Chong Meng, Z. Yang
We report experimental and theoretical investigations of coherent perfect channeling (CPC), a process that two incoming coherent waves in waveguides are completely channeled into o…
High Ultrasonic Transmission Loss Metasurfaces in Water
Liang Sun, Ning Wang, Chong Meng +1
We report the experimental demonstration of a class of ultrasonic metasurfaces made of patterned silicon thin wafers partially covered by Si3N4 film that exhibit over 24 dB of soun…
Hybrid membrane resonators for multiple frequency asymmetric absorption and reflection in large waveguide
Caixing Fu, Xiaonan Zhang, Min Yang +2
We report that Hybrid membrane resonators (HMRs) made of a decorated membrane resonator backed by a shallow cavity can function as Helmholtz resonators (HRs) when mounted on the si…
Acoustic Coherent Perfect Absorbers as Sensitive Null Detectors
Chong Meng, Xiaonan Zhang, Suet To Tang +2
We report the experimental realization of acoustic coherent perfect absorption (CPA) of four symmetric scatterers of very different structures. The only conditions necessary for th…
Subwavelength total acoustic absorption with degenerate resonators
Min Yang, Chong Meng, Caixing Fu +3
We report the experimental realization of perfect sound absorption by sub-wavelength monopole and dipole resonators that exhibit degenerate resonant frequencies. This is achieved t…
Sound Absorption by Subwavelength Membrane Structures: A Generalized Perspective
Min Yang, Yong Li, Chong Meng +4
Decorated membrane, comprising a thin layer of elastic film with small rigid platelets fixed on top, has been found to be an efficient absorber of low frequency sound. In this work…
