Acoustic Metagrating Circulators: Nonreciprocal, Robust, and Tunable Manipulation with Unitary Efficiency
Lijuan Fan, Jun Mei
Nonreciprocal signal operation is highly desired for various acoustic applications, where protection from unwanted backscattering can be realized so that transmitting and receiving…
Acoustic frequency filter based on anisotropic topological phononic crystals
Ze-Guo Chen, Jiajun Zhao, Jun Mei +1
There are growing efforts in constructing topological edge states in classical wave system. However, most of the work study the existence, creation and properties of the edge state…
Pseudo-time-reversal symmetry and topological edge states in two-dimensional acoustic crystals
Jun Mei, Ze-Guo Chen, Ying Wu
We propose a simple two-dimensional acoustic crystal to realize topologically protected edge states for acoustic waves. The acoustic crystal is composed of a triangular array of co…
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…
A Lumped Model for Rotational Modes in Phononic Crystals
Pai Peng, Jun Mei, Ying Wu
We present a lumped model for the rotational modes induced by the rotational motion of individual scatterers in two-dimensional phononic crystals comprised of square arrays of soli…
Do Linear Dispersions of Classical Waves Mean Dirac Cones?
Jun Mei, Ying Wu, C. T. Chan +1
By using the \vec{k}\cdot\vec{p} method, we propose a first-principles theory to study the linear dispersions in phononic and photonic crystals. The theory reveals that only those…
