Flat beam optimization of 1-bit Reflectarray by means of Social Network Optimization

Reconfigurable reflectarray is an important topic in antenna research. Different kind of objectives can be identified for these systems, from beam scanning to adaptive beam shaping. In this paper 1-bit reflectarray has been optimized in order to obtain a flat beam. The reconfiguration capability of the array has been exploited in order to change properly the desired beam width. The optimization process has been done by means of a novel Evolutionary Optimization Algorithms, Social Network Optimization, suited for binary optimization problems.
