The proposed iterative method aims at array thinning and optimization of element positions and weights by minimizing the side-lobes level. Selected examples are included, which demonstrate the effectiveness and the design flexibility of the proposed method in the framework of electromagnetic synthesis of linear arrays. date: 2004-08 date_type: published institution: University of Trento department: informaticat refereed: FALSE referencetext: [1] C.
