Gradient Impedance Matching Layers Enable Broadband Water-Air Sound Transmission
Ping Zhou, Han Jia, Yafeng Bi +4
Efficient sound transmission across the water-air interface has always been expected in the field of ocean exploration. However, the existing researches are mainly concentrated on…
Acoustic Metafluid for Independent manipulation of the Mass Density and Bulk Modulus
Yafeng Bi, Ping Zhou, Han Jia +4
Tuning the mass density and bulk modulus independently is the key to manipulate the propagation of sound wave. Acoustic metamaterials provide a feasible method to realize various a…
Acoustic Structure Inverse Design and Optimization Using Deep Learning
Xuecong Sun, Han Jia, Yuzhen Yang +4
From ancient to modern times, acoustic structures have been used to control the propagation of acoustic waves. However, the design of the acoustic structures has remained widely a…
Experimental demonstration of asymmetric diffraction based on a passive parity-time-symmetric acoustic grating
Yuzhen Yang, Han Jia, Yafeng Bi +2
Passive parity-time-symmetric medium provides a feasible scheme to investigate non-Hermitian systems experimentally. Here, we design a passive PT-symmetric acoustic grating with a…
Quasi isotropic underwater acoustic carpet cloak based on latticed pentamode metafuid
Zhaoyong Sun, Xuecong Sun, Han Jia +2
In this work, we present a practical design of quasi isotropic underwater acoustic carpet cloak with pentamode microstructure. The quasi conformal transformation is not only used t…
Experimental demonstration of three-dimensional broadband underwater acoustic carpet cloak
Yafeng Bi, Han Jia, Zhaoyong Sun +3
We present the design, architecture and detailed performance of a three-dimensional (3D) underwater acoustic carpet cloak (UACC). The proposed system of the 3D UACC is an octahedra…
Design and demonstration of an acoustic right-angle bend
Wenjia Lu, Han Jia, Yafeng Bi +2
In this paper, we design, fabricate and experimentally characterize a broadband acoustic right-angle bend device in air. Perforated panels with various hole-sizes are used to const…
Broadband solid cloak for underwater acoustics
Yi Chen, Mingye Zheng, Xiaoning Liu +5
Application of transformation theory to underwater acoustics has been a challenging task because highly anisotropic density is unachievable in water. A possible strategy is to expl…
