Inverse scattering for the one-dimensional Helmholtz equation with piecewise constant wave speed
Sophia Bugarija, Peter C. Gibson, Guanghui Hu +2
This paper analyzes inverse scattering for the one-dimensional Helmholtz equation in the case where the wave speed is piecewise constant. Scattering data recorded for an arbitraril…
Inverse random source scattering for the Helmholtz equation with attenuation
Peijun Li, Xu Wang
In this paper, a new model is proposed for the inverse random source scattering problem of the Helmholtz equation with attenuation. The source is assumed to be driven by a fraction…
An inverse random source problem for the time fractional diffusion equation driven by a fractional Brownian motion
Xiaoli Feng, Peijun Li, Xu Wang
This paper is concerned with the mathematical analysis of the inverse random source problem for the time fractional diffusion equation, where the source is assumed to be driven by…
Elastic scattering from rough surfaces in three dimensions
Guanghui Hu, Peijun Li, Yue Zhao
Consider the elastic scattering of a plane or point incident wave by an unbounded and rigid rough surface. The angular spectrum representation (ASR) for the time-harmonic Navier eq…
An inverse acoustic-elastic interaction problem with phased or phaseless far-field data
Heping Dong, Jun Lai, Peijun Li
Consider the scattering of a time-harmonic acoustic plane wave by a bounded elastic obstacle which is immersed in a homogeneous acoustic medium. This paper concerns an inverse acou…
Convergence of an adaptive finite element DtN method for the elastic wave scattering by periodic structures
Peijun Li, Xiaokai Yuan
Consider the scattering of a time-harmonic elastic plane wave by a periodic rigid surface. The elastic wave propagation is governed by the two-dimensional Navier equation. Based on…
Convergence of an adaptive finite element DtN method for the elastic wave scattering problem
Peijun Li, Xiaokai Yuan
Consider the scattering of an elastic plane wave by a rigid obstacle, which is immersed in a homogeneous and isotropic elastic medium in two dimensions. Based on a Dirichlet-to-Neu…
