Journal ArticleDOI
Experimental demonstration of anomalous Floquet topological insulator for sound.
TL;DR: Experimental demonstration of anomalous Floquet topological insulator for sound: a strongly coupled metamaterial ring lattice that supports one-way propagation of pseudo-spin-dependent edge states under T-symmetry.
Journal ArticleDOI
Observation of elastic topological states in soft materials
TL;DR: The on-demand reversible switch in topological phase has been achieved by changing filling ratio, tension, and/or compression of the elastic metamaterials, and the formation and dynamic tunability of topological interface states by mechanical deformation is demonstrated.
Journal ArticleDOI
Topological interface modes in local resonant acoustic systems
TL;DR: In this article, the topological properties of subwavelength bands in a local resonant acoustic system and elaborate the band-structure evolution using a spring-mass model were studied.
Journal ArticleDOI
Ultrasonic super-oscillation wave-packets with an acoustic meta-lens
Ya-Xi Shen,Yu-Gui Peng,Yu-Gui Peng,Feiyan Cai,Kun Huang,Degang Zhao,Cheng-Wei Qiu,Hairong Zheng,Xue-Feng Zhu +8 more
TL;DR: An ultrasonic meta-lens for generating super-oscillation acoustic wave-packets with different spatial momenta and then superimposing them to a diffraction-limit-broken spot is proposed, visually represented by the ring-shaped trapping of tiny particles.
Journal ArticleDOI
Zero-n photonic band gap in a quasiperiodic stacking of positive and negative refractive index materials
Jing Li,Degang Zhao,Zhengyou Liu +2 more
TL;DR: In this paper, a zero-n¯ gap was found in the photonic spectra of a quasiperiodic structure and the self-similar and non-self-similar wave functions were exhibited at frequencies close to the zero- n¯ gap.
