A novel Newton method for inverse elastic scattering problems
Yan Chang, Yukun Guo, Hongyu Liu +1
This work is concerned with an inverse elastic scattering problem of identifying the unknown rigid obstacle embedded in an open space filled with a homogeneous and isotropic elasti…
Mathematical and numerical study of an inverse source problem for the biharmonic wave equation
Yan Chang, Yukun Guo, Tao Yin +1
In this paper, we study the inverse source problem for the biharmonic wave equation. Mathematically, we characterize the radiating sources and non-radiating sources at a fixed wave…
Jointly determining the point sources and obstacle from Cauchy data
Deyue Zhang, Yan Chang, Yukun Guo
A numerical method is developed for recovering both the source locations and the obstacle from the scattered Cauchy data of the time-harmonic acoustic field. First of all, the inci…
Recovering source location, polarization, and shape of obstacle from elastic scattering data
Yan Chang, Yukun Guo, Hongyu Liu +1
We consider an inverse elastic scattering problem of simultaneously reconstructing a rigid obstacle and the excitation sources using near-field measurements. A two-phase numerical…
