Convexification numerical algorithm for a 2D inverse scattering problem with backscatter data

24 Feb 2020 Truong Trung Nguyen Dinh-Liem Klibanov Michael

This paper is concerned with the inverse scattering problem which aims to determine the spatially distributed dielectric constant coefficient of the 2D Helmholtz equation from multifrequency backscatter data associated with a single direction of the incident plane wave. We propose a globally convergent convexification numerical algorithm to solve this nonlinear and ill-posed inverse problem... (read more)
