Reflected continuously tunable acoustic metasurface with rotatable space coiling-up structure
Haozhen Zou, Yanlong Xu, Pan Li +1
In this paper, we propose a continuously tunable acoustic metasurface composed of identical anisotropic resonant units, each of which contains a rigid pedestal and a rotatable incl…
Ultra-thin Underwater Acoustic Metasurface with Multiply Resonant Units
Haozhen Zou, Pan Li, Pai Peng
This paper describes a new kind of acoustic metasurface with multiply resonant units, which have previously been used to induce multiple resonances and effectively produce negative…
A novel zero-frequency seismic metamaterial
Yi Zeng, Pai Peng, Qiu-Jiao Du +1
A zero-frequency seismic metamaterial (ZFSM) consisting of a three-component seismic metamaterial plate and a half space is proposed to attenuate ultra-low frequency seismic surfac…
Reflected wavefront manipulation by acoustic metasurface with anisotropic local resonant units
Meiyu Liu, Pan Li, Pai Peng
In this work, we develop the gradient metasurface is constructed of a locally anisotropic resonant structure, comprising a steel cylinder with an elliptical rubber coating embedded…
Space-coiling Acoustic Metasurface with Independent Modulations of Phase and Amplitude
Pan Li, Qiujiao Du, Meiyu Liu +1
In this work, we propose a design of acoustic meta-surfaces in sub-wavelength scale enabling independent modulations of phase and amplitude. Each unit cell of the acoustic meta-sur…
Manipulate Elastic Wave Modes by an Ultrathin Three-component Elastic Metasurface
Pai Peng, Cheng Feng, Kangcheng Zhou
We design a two-dimensional ultra-thin elastic metasurface consisting of steel cores coated with elliptical rubbers embedded in epoxy matrix, capable of manipulating bulk elastic w…
