An Accelerated Nonlinear Contrast Source Inversion Scheme for Sparse Electromagnetic Imaging

An efficient nonlinear contrast source inversion scheme for electromagnetic imaging of sparse two-dimensional investigation domains is proposed. To avoid generating a sequence of linear sparse optimization problems, the non-linearity is directly tackled using the nonlinear Landweber (NLW) iterations...
