Efficient, High-purity, Robust Sound Frequency Conversion with a Linear Metasurface
Chengbo Hu, Wei Wang, Jincheng Ni +5
The intrinsic limitation of the material nonlinearity inevitably results in the poor mode purity, conversion efficiency and real-time reconfigurability of the generated harmonic wa…
Robust zero-energy states in two-dimensional Su-Schrieffer-Heeger topological insulators
Zhang-Zhao Yang, An-Yang Guan, Wen-Jie Yang +2
The Su-Schrieffer-Heeger (SSH) model on a two-dimensional square lattice has been considered as a significant platform for studying topological multipole insulators. However, due t…
A General Method to Design Acoustic Higher-Order Topological Insulators
An-Yang Guan, Zhang-Zhao Yang, Xin-Ye Zou +1
Acoustic systems that are without limitations imposed by the Fermi level have been demonstrated as significant platform for the exploration of fruitful topological phases. By surro…
Topological Classical Systems with Generalized Chiral Symmetry
Zhang-Zhao Yang, An-Yang Guan, Xin-Ye Zou +1
The bulk band topology of symmetry invariant adiabatic systems in the thermodynamic limit are considered to be determined by the hopping energy. In this work, we present that in cl…
Meta-neural-network for Realtime and Passive Deep-learning-based Object Recognition
Jingkai Weng, Yujiang Ding, Chengbo Hu +4
Deep-learning recently show great success across disciplines yet conventionally require time-consuming computer processing or bulky-sized diffractive elements. Here we theoreticall…
Acoustic manipulation through zero-thickness perforated plane with strong-coupling effects
Liu-Ming Hao, Xin-Ye Zou, Bin Liang +1
How to manipulate acoustic waves through thinner structures is always a challenging problem due to the linear proportional relationship between the structural thickness and the aco…
