Direct imaging methods for reconstructing a locally rough interface from phaseless total-field data or phased far-field data
Long Li, Jiansheng Yang, Bo Zhang +1
This paper is concerned with the problem of inverse scattering of time-harmonic acoustic plane waves by a two-layered medium with a locally rough interface in 2D. A direct imaging…
A Nyström Method for Scattering by a Two-layered Medium with a Rough Boundary
Haiyang Liu, Long Li, Jiansheng Yang +2
This paper is concerned with problems of scattering of time-harmonic acoustic waves by a two-layered medium with a non-locally perturbed boundary (called a rough boundary in this p…
Uniform far-field asymptotics of the two-layered Green function in 2D and application to wave scattering in a two-layered medium
Long Li, Jiansheng Yang, Bo Zhang +1
In this paper, we establish new results for the uniform far-field asymptotics of the two-layered Green function (together with its derivatives) in 2D in the frequency domain. To th…
Piecewise-analytic interfaces with weakly singular points of arbitrary order always scatter
Long Li, Guanghui Hu, Jiansheng Yang
It is proved that an inhomogeneous medium whose boundary contains a weakly singular point of arbitrary order scatters every incoming wave. Similarly, a compactly supported source t…
Imaging of buried obstacles in a two-layered medium with phaseless far-field data
Long Li, Jiansheng Yang, Bo Zhang +1
The inverse problem we consider is to reconstruct the location and shape of buried obstacles in the lower half-space of an unbounded two-layered medium in two dimensions from phase…
Unique determination of a penetrable scatterer of rectangular type for inverse Maxwell equations by a single incoming wave
Guanghui Hu, Long Li, Jun Zou
This work is concerned with an inverse electromagnetic scattering problem in two dimensions. We prove that in the TE polarization case, the knowledge of the electric far-field patt…
