Absence of the analytic continuation of elastic transmission eigenfunctions at rectangular corners
Jianli Xiang, Guanghui Hu
We study time harmonic scattering problems in linear elasticity in . We show that certain penetrable scatterers with rectangular corners scatter every incident wave…

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…
