Paper Title
Inverse Electromagnetic Scattering by Combining Subspace-based Algorithms
Abstract
This paperdiscusses an inverse scattering problem for the reconstruction of permittivity distribution of twodimensional
dielectric objects.Based on the boundary condition and the measured scattered field, a set of nonlinear integral
equation is derived and the imaging problem is reformulated into optimization problem. We solved the problem by
combining subspace-basedalgorithmand self-adaptive dynamic differential evolution (SADDE). Numerical results showthat
the permittivity distribution of the dielectric objectsis well reconstructed by SADDE.
