N2 - A method to reconstruct the source current from far‐field data in terms of electric and magnetic point dipoles is described. The inverse problem of solving the source from a known electromagnetic far‐field pattern is carried out by a combination of genetic algorithm and local optimizers. The source is modelled by a small number of point dipoles, the locations, amplitudes and types of which are determined by minimizing the difference between the field of the ensemble and the targeted pattern. Uniqueness is ensured by limiting the number of dipoles together with an appropriately weighted minimum energy condition. A general description of the method applicable to antenna analysis and synthesis is given and three examples of its practical use are presented.
