A novel effective model for solving 3D forward scattering problems in a homogeneous background

A new model for the solution of 3D forward scattering problems, particularly suitable for lossy scenarios, is presented. The proposed model is a suitable extension to the vectorial case of the contrast source-extended Born method recently proposed with reference to the 2D scalar case. Based on the proposed model, a new series is introduced which represents a convenient may to solve the forward problem in many cases. Moreover, analytical tools are provided to foresee the actual behavior of the series; they are also of interest for the corresponding inverse problem.
