Convergent and efficient iteratively regularized contrast source inversion-type methods for inverse medium scattering problems
Qiao Hu, Bo Zhang, Haiwen Zhang
The contrast source inversion (CSI) method and the subspace-based optimization method (SOM) are first proposed in 1997 and 2009, respectively, and subsequently modified. The two me…

A deep learning approach to inverse medium scattering: Learning regularizers from a direct imaging method
Kai Li, Bo Zhang, Haiwen Zhang
This paper aims to solve numerically the two-dimensional inverse medium scattering problem with far-field data. This is a challenging task due to the severe ill-posedness and stron…
