The Generalized Intersection Approach for Electromagnetic Array Antenna Beam-Shaping Synthesis: A Review

This work presents a review of the generalized intersection approach (GIA) for electromagnetic array antenna beam-shaping synthesis. After briefly describing mechanics classical IA, we show extensions to IA that make GIA more powerful algorithm. In short, these improvements consist in working with squared field magnitude improve convergence properties algorithm, and use general minimization algorithm backward projection allows extend scope optimizing variables beyond those directly related at aperture. Three optimization examples using are presented showcase its capabilities near far synthesis variety arrays: transmitarray, aperiodic phased-array reflectarray. Finally, carry out literature including origin, different flavours, development, current future
