The nature of reflectarray (RA) optimization problems is intrinsically multi-target and therefore the use of a multi-objective optimization scheme is particularly convenient, although it can be computationally expensive. In this paper some considerations on the characterization and optimization of a RA are presented. The results of the use of efficient approaches for the modeling of the planar RA...
The design of printed reflectarray antennas (RAs) could be quite complex and computationally expensive, since the need of providing high performances and satisfying requirements that could be also in contrast each other could require the use of a large number of re-radiating advanced element configurations. A possible strategy for the RA design could be therefore of carrying it out adopting an evolutionary...
In this paper an Artificial Neural Network (ANN) is introduced in order to speed up the optimized design procedure of a printed Reflectarray. The ANN is used to model the reflecting behaviour of patch radiator as a function of its geometric parameters, the angle of incidence and the frequency. When used in the RA design process, the reflection coefficient approximated with the ANN produces results...
The increasing interest among the scientific community on soft computing and optimization techniques in recent years leads to develop effective ad-hoc procedures for electromagnetic structures modelling, often based on evolutionary iterative algorithms. In fact, in most of engineering problems, numerical simulations could be very computationally expensive. An example of this is for instance the design...
