A highly accurate boundary integral method for the elastic obstacle scattering problem
Heping Dong, Jun Lai, Peijun Li
Consider the scattering of a time-harmonic plane wave by a rigid obstacle embedded in a homogeneous and isotropic elastic medium in two dimensions. In this paper, a novel boundary…
On Wellposedness and Convergence of UPML method for analyzing wave scattering in layered media
Wangtao Lu, Jun Lai, Haijun Wu
This paper proposes a novel method to establish the wellposedness and convergence theory of the uniaxial-perfectly-matched-layer (UPML) method in solving a two-dimensional acoustic…
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…
Inverse obstacle scattering problem for elastic waves with phased or phaseless far-field data
Heping Dong, Jun Lai, Peijun Li
This paper concerns an inverse elastic scattering problem which is to determine the location and the shape of a rigid obstacle from the phased or phaseless far-field data for a sin…
