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…

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…
