DOI: 10.1109/tmtt.2017.2731948
Abstract: Solving inverse scattering problems (ISPs) for targets with high contrasts and/or large dimensions suffer from severe ill-posedness and strong nonlinearity. Recently, a family of new integral equations (NIE) has been proposed to tackle such problems,… read more here.

DOI: 10.2989/16073606.2025.2505506
Abstract: Abstract This paper considers an inverse problem to find the space-dependent source term and initial data simultaneously in a time-fractional diffusion equation. This inverse problem is usually ill-posed, that is, small errors in the measurement… read more here.
