Towards this goal, the synthesis problem is formulated as an inverse source one, and a closed?form expression solution is derived to compute the non?radiating current components able to modify the geometry of the reflective surface without altering the desired radiation features. Some representative numerical benchmarks are shown to assess the proposed synthesis methodology, as well as to verify its flexibility in realizing "forbidden?regions" of arbitrary shape.}, url = {http://www.eledia.org/students-reports/790/} }
