Abstract: Multi-layer array design is dominated by the computational cost of the radiated fields using full-wave methods. Among others the EAML activity includes new developments directed to reduce this computational cost by means of various acceleration techniques, generally based on the rearrangement of the solution matrix following the physical characteristics of the array. The use of these techniques allows a reduction of the calculation time by a two or three order of magnitude, thereby allowing the optimisation only of the array excitations but also of the array layout and element design. Furthermore the availability of several acceleration methods within a same tool offers the opportunity to select the most suitable combination for the particular array at hand.
