Broadband Reflective Elastic Mode Conversion Enabled by a Single Row of Inclined Long-Slits
Kaifei Feng, Weidong Wang, Yucheng Gao +4
Broadband longitudinal-to-transverse mode conversion under normal incidence remains difficult to achieve, especially with structurally simple designs. Numerical simulations show th…
Lines of Bound States in the Continuum in a Phononic Crystal Slab
Lin Yang, Riyi Zheng, Sheng Zhang +7
We demonstrate that bound states in the continuum (BICs) form continuous lines along high-symmetry directions of momentum space in a simple phononic crystal slab. Contrary to commo…
Complete mode conversion for elastic waves reflected by elastic metamaterial slab with double hexapole resonances
Di Liu, Wenjie Yu, Qiujiao Du +2
In this study, we investigate the phenomenon of mode conversion in elastic bulk waves using coupled hexapole resonances. A metamaterial slab is proposed enabling the complete conve…
Broadband inverted T-shaped seismic metamaterial
Yi Zeng, Shu-Yan Zhang, Hong-Tao Zhou +6
Seismic metamaterials (SMs) are expected to assist or replace traditional isolation systems owing to their strong attenuation of seismic waves. In this paper, a one-dimensional inv…
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…
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…
Reflected wavefront manipulation by acoustic metasurface with anisotropic local resonant units
Pai Peng, Meiyu Liu, Pan Li
Metasurfaces with planar profile and wave front shaping capabilities would be ideally suitable to improve the performance of acoustic wave-based applications. It is significant tha…
