Acoustic Pressure Monopole, Velocity Monopole, and Hybrid Monopole
Suet To Tang, Xiaonan Zhang, Chong Meng +1
We show that there are two types of acoustic monopoles, namely the pressure monopoles (PMs) and the velocity monopoles (VMs). Under one wave incidence, only the pressure field near…
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…
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…
