Evolutionary algorithms applications for inverse scattering using Gaussian beams

In this work we attempt to overcome the two main limitations of the generic inverse scattering problem: the size and the ill-posed nature of the problem. We use a solver that is based on the discrete Gaussian beam summation method and apply it for the special case of a smoothly varying inhomogeneous medium. In order to overcome the need to perform simplifying approximations for the propagating medium, we use evolutionary algorithms for the optimization scheme. Reconstruction results for several configurations are presented.
