Inverse obstacle scattering with a single moving emitter
Yu Sun, Bo Chen, Peng Gao +2
This paper is concerned with time domain forward scattering and inverse scattering problems with a single moving point source as the emitter. Approximate solutions are provided for…

Inverse problems for elastic wave from Partial Cauchy Data: Uniqueness and Co-inversion for Shape and Impedance Function
Yao Sun, Yan Chang, Yukun Guo
We consider an inverse problem for the elastic wave of simultaneously reconstructing the impedance and the geometric information of the bounded body that is occupied by a homogeneo…

A novel sampling method for time domain acoustic inverse source problems
Jiaru Wang, Bo Chen, Qingqing Yu +1
This paper is concerned with the inverse acoustic scattering problems of reconstructing time-dependent multiple point sources and sources on a curve of the form $λ(t)τ(x)δ_L(x)…
