A Weighted Sampling Method for Inverse Medium Problem with Limited Aperture
Fuqun Han, Kazufumi Ito
Inverse medium scattering problems arise in many applications, but in practice, the measurement data are often restricted to a limited aperture by physical or experimental constrai…

A Direct Sampling Method and Its Integration with Deep Learning for Inverse Scattering Problems with Phaseless Data
Jianfeng Ning, Fuqun Han, Jun Zou
We consider in this work an inverse acoustic scattering problem when only phaseless data is available. The inverse problem is highly nonlinear and ill-posed due to the lack of the…
