An iterative method for two-dimensional problems with multiple scatterers is presented. Spectral techniques are used to characterise a scatterer by its transfer function. To obtain this transfer function physical optics and the method of moments have been used. An iterative method analysing the existence of a new object at each new iteration is outlined. The method produces combined transfer functions that give the response of the multiple scattering problem to several incident fields. A useful alternative iteration for clumped groups of scatterers is also presented. Results for a parabolic reflector, a Cassegrain structure and a horn for TM incidence are analysed and comparison with theoretical data is discussed. Finally, the extension of the method for the TE case and for 3D problems is outlined
