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…
Underwater Acoustic Multiplexing Communication by Pentamode Metasurface
Zhaoyong Sun, Yu Shi, Xuecong Sun +4
As the dominant information carrier in water, acoustic wave is widely used for underwater detection, communication and imaging. Even though underwater acoustic communication has be…
Sound Localization and Separation in Three-dimensional Space Using a Single Microphone with a Metamaterial Enclosure
Xuecong Sun, Han Jia, Zhe Zhang +3
Conventional approaches to sound localization and separation are based on microphone arrays in artificial systems. Inspired by the selective perception of human auditory system, we…
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 of an underwater acoustic bend by pentamode metafluid
Zhaoyong Sun, Han Jia, Yi Chen +2
We design an impedance matching underwater acoustic bend with pentamode microstructure. The proposed bend is assembled by pentamode lattice. The effective density and compressive m…
Design of an impedance matching acoustic bend
Yuzhen Yang, Han Jia, Wenjia Lu +2
We propose the design of an impedance matching acoustic bend in this article. The bending structure is composed of sub-wavelength unit cells with perforated plates and side pipes,…
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…
The Quasi-normal Modes of Charged Scalar Fields in Kerr-Newman black hole and Its Geometric Interpretation
Peng Zhao, Yu Tian, Xiaoning Wu +1
It is well-known that there is a geometric correspondence between high-frequency quasi-normal modes (QNMs) and null geodesics (spherical photon orbits). In this paper, we generaliz…
Doubled Conformal Compactification
Zhao Yong Sun, Yu Tian
We use Weyl transformations between the Minkowski spacetime and dS/AdS spacetime to show that one cannot well define the electrodynamics globally on the ordinary conformal compacti…
