To this aim, the synthesis problem at hand is formulated as an inverse source one, then solved in an analytical way. Owing to the non?uniqueness of the solution, the existence of non?radiating current components are successfully exploited as additional degrees?of?freedom to match both radiation and aperture geometry constraints. Selected representative numerical experiments are presented to verify the effectiveness of the developed synthesis method.}, url = {http://www.eledia.org/students-reports/789/}, keywords = {Geometry-constrained design, inverse source (IS) problems, nonradiating (NR) currents, reflectarray current synthesis.} }
