%X In this work, the design of new‐generation reflectarrays is dealt with. To this end, an 
innovative  synthesis  technique  is  developed  to  design  the  reflectarray  surface 
currents that satisfy both radiation and arbitrary geometry constraints. Accordingly, 
the  reflectarray  design  is  formulated  as  an  inverse  source  problem,  and  the  non‐
radiating contribution of the current is profitably synthesized in order to cancel the 
overall  current  within  selected  "forbidden  regions".  Some  preliminary  results  are 
presented to assess the effectiveness of the developed approach.
