Abstract

A method inspired from the Born series is developed to evaluate the source-type integral equation in 2-D scattering problems. Starting from a low contrast profile for the complex permittivity of the scattering object, the method iteratively increases the profile towards the real one. In every iteration, the field change due to the profile increment is obtained from a Born like series, in which the scattered field from the previous iteration is used as the first approximation. The application of the method to 2-D scattering problems shows it is capable to evaluate the scattered field of relatively high contrast objects with reasonable accuracy
