SNO and mBBO Optimization Methods for beam scanning Reflectarray Antennas

In these years high gain antennas have become very interesting from an application point of view, in particular the possibility to use a Reflectarray Antenna as a new technology of reflector has been studied by researchers. One of the most alluring features of RA is that modifying the phase of its re-radiating element is possible to obtain the desired pattern in the desired direction. In this work the possibility to obtain a scanning beam RA has been studied applying two evolutionary algorithms: the SNO and the mBBO.
