An inverse spectral problem for a damped wave operator
Gang Bao, Xiang Xu, Jian Zhai
This paper proposes a new and efficient numerical algorithm for recovering the damping coefficient from the spectrum of a damped wave operator, which is a classical Borg-Levinson i…
An adaptive finite element DtN method for the elastic wave scattering by biperiodic structures
Gang Bao, Xue Jiang, Peijun Li +1
Consider the scattering of a time-harmonic elastic plane wave by a bi-periodic rigid surface. The displacement of elastic wave motion is modeled by the three-dimensional Navier equ…
Stability for the multifrequency inverse medium problem
Gang Bao, Faouzi Triki
The solution of a multi-frequency 1d inverse medium problem consists of recovering the refractive index of a medium from measurements of the scattered waves for multiple frequencie…
Inverse scattering by a random periodic structure
Gang Bao, Yiwen Lin, Xiang Xu
This paper develops an efficient numerical method for the inverse scattering problem of a time-harmonic plane wave incident on a perfectly reflecting random periodic structure. The…
Recovering simultaneously a potential and a point source from Cauchy data
Gang Bao, Yuantong Liu, Faouzi Triki
This paper is devoted to the inverse problem of recovering simultaneously a potential and a point source in a Shrödinger equation from the associated nonlinear Dirichlet to Neumann…
An adaptive finite element DtN method for the three-dimensional acoustic scattering problem
Gang Bao, Mingming Zhang, Bin Hu +1
This paper is concerned with a numerical solution of the acoustic scattering by a bounded impenetrable obstacle in three dimensions. The obstacle scattering problem is formulated a…
