Geometrical and topological properties of transmission resonance and artificial mirage
Youjun Deng, Hongyu Liu, Xianchao Wang +1
Transmission eigenfunctions are certain interior resonant modes that are of central importance to the wave scattering theory. In this paper, we present the discovery of novel globa…
Simultaneous recovery of surface heat flux and thickness of a solid structure by ultrasonic measurements
Youjun Deng, Hongyu Liu, Xianchao Wang +2
This paper is concerned with a practical inverse problem of simultaneously reconstructing the surface heat flux and the thickness of a solid structure from the associated ultrasoni…
Three-dimensional Elastic Scattering Coefficients and Enhancement of the Elastic Near Cloaking
Hongyu Liu, Wing Yan Tsui, Abdul Wahab +1
This paper is concerned with the elastic near cloaking for the Lamé system in three-dimensions using the notion of elastic scattering coefficients (ESC). Accordingly, the ESC of ar…
Surface-localized transmission eigenstates, super-resolution imaging and pseudo surface plasmon modes
Yat Tin Chow, Youjun Deng, Youzi He +2
We present the discovery of a novel and intriguing global geometric structure of the (interior) transmission eigenfunctions associated with the Helmholtz system. It is shown in gen…
Reconstruction of acoustic sources from multi-frequency phaseless far-field data
Deyue Zhang, Yukun Guo, Fenglin Sun +1
We consider the inverse source problem of determining an acoustic source from multi-frequency phaseless far-field data. By supplementing some reference point sources to the inverse…
On a novel inverse scattering scheme using resonant modes with enhanced imaging resolution
Hongyu Liu, Xiaodong Liu, Xianchao Wang +1
We develop a novel wave imaging scheme for reconstructing the shape of an inhomogeneous scatterer and we consider the inverse acoustic obstacle scattering problem as a prototype mo…
