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…
Direct and inverse time-harmonic elastic scattering from point-like and extended obstacles
Guanghui Hu, Andrea Mantile, Mourad Sini +1
This paper concerns the time-harmonic direct and inverse elastic scattering by an extended rigid elastic body surrounded by a finite number of point-like obstacles. We first justif…
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…
Uniqueness to some inverse source problems for the wave equation in unbounded domains
Guanghui Hu, Yavar Kian, Yue Zhao
This paper is concerned with inverse acoustic source problems in an unbounded domain with dynamical boundary surface data of Dirichlet kind. The measurement data are taken at a sur…
Bayesian Approach to Inverse Time-harmonic Acoustic Scattering with Phaseless Far-field Data
Zhipeng Yang, Xinping Gui, Ju Ming +1
This paper is concerned with inverse acoustic scattering problem of inferring the position and shape of a sound-soft obstacle from phaseless far-field data. We propose the Bayesian…
Inverse source problems in an inhomogeneous medium with a single far-field pattern
Guanghui Hu, Jingzhi Li
This paper concerns time-harmonic inverse source problems with a single far-field pattern in two dimensions, where the source term is compactly supported in an a priori given inhom…
Inverse moving source problem for fractional diffusion(-wave) equations: Determination of orbits
Guanghui Hu, Yikan Liu, Masahiro Yamamoto
This paper is concerned with the inverse problem on determining an orbit of the moving source in a fractional diffusion(-wave) equations in a connected bounded domain of $\mathbb R…
Uniqueness and factorization method for inverse elastic scattering with a single incoming wave
Johannes Elschner, Guanghui Hu
The first part of this paper is concerned with the uniqueness to inverse time-harmonic elastic scattering from bounded rigid obstacles in two dimensions. It is proved that a connec…
Time-harmonic acoustic scattering from a non-locally perturbed trapezoidal surface
Wangtao Lu, Guanghui Hu
This paper is concerned with acoustic scattering from a sound-soft trapezoidal surface in two dimensions. The trapezoidal surface is supposed to consist of two horizontal half-line…
