Recovering the sources in the stochastic wave equations from multi-frequency far-field patterns
Yan Chang, Yukun Guo, Zhipeng Yang +1
This paper concerns the inverse source scattering problems of recovering random sources for acoustic and elastic waves. The underlying sources are assumed to be random functions dr…
Identifying an acoustic source in a two-layered medium from multi-frequency phased or phaseless far-field patterns
Yan Chang, Yukun Guo, Yue Zhao
This paper presents a method for reconstructing an acoustic source located in a two-layered medium from multi-frequency phased or phaseless far-field patterns measured on the upper…
The inverse obstacle scattering with incident tapered waves
Deyue Zhang, Mengjiao Bai, Yan Chang +1
This paper is concerned with the reconstruction of the shape of an acoustic obstacle. Based on the use of the tapered waves with very narrow widths illuminating the obstacle, the b…
Direct and Inverse scattering in a three-dimensional planar waveguide
Yan Chang, Yukun Guo, Yue Zhao
In this paper, we study the direct and inverse scattering of the Schrödinger equation in a three-dimensional planar waveguide. For the direct problem, we derive a resonance-free re…
Inverse source problem of the biharmonic equation from multi-frequency phaseless data
Yan Chang, Yukun Guo, Yue Zhao
This work deals with an inverse source problem for the biharmonic wave equation. A two-stage numerical method is proposed to identify the unknown source from the multi-frequency ph…
