Abstract
This work presents an innovative methodology for synthesizing the reflectarray surface current that is able to meet (at the same time) radiation and user‐defined geometrical constraints. Towards this end, by suitably formulating the reflectarray design as an inverse source (IS) problem, the non‐radiating current components flowing on the reflective surface are profitably determined in order to cancel the overall current in correspondence to selected sub‐regions (i.e., "forbidden‐regions") of the antenna surface without modifying the desired radiation features. Representative numerical results are shown to validate the effectiveness of the developed synthesis method.
