Uniqueness in determining a convex polygonal source of an elastic body
Jianli Xiang
In this work, we consider the time-harmonic inverse elastic source problem of a fixed frequency for the Navier equation in two dimensions. We show that a convex polygon can be uniq…

Uniqueness to inverse acoustic and elastic medium scattering problems with hyper-singular source method
Chun Liu, Guanghui Hu, Jianli Xiang +1
This paper is concerned with inverse scattering problems of determining the support of an isotropic and homogeneous penetrable body from knowledge of multi-static far-field pattern…

Uniqueness in determining rectangular grating profiles with a single incoming wave (Part II): TM polarization case
Jianli Xiang, Guanghui Hu
This paper is concerned with an inverse transmission problem for recovering the shape of a penetrable rectangular grating sitting on a perfectly conducting plate. We consider a gen…
