Continuously Tunable Acoustic Metasurface with Rotatable Anisotropic Three-component Resonators
Pan Li, Yunfan Chang, Qiujiao Du +3
We propose a tunable acoustic metasurface consisting of identical units. And units are rotatable anisotropic three-component resonators, which can induce the non-degenerate dipolar…
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…
