Design of multiple-feed lens antennas requires multivariate and multi-objective optimization processes, which can be accelerated by PSO algorithms. However, the PSO algorithm often fails to achieve optimal results with limited computation resources s

The separation of multiple feed streams with some common components using sequences of distillation columns produces a rich space of alternatives that must be considered. In this work, we present the main structural characteristics of sequences gener

Multi-beam antennas based on quasi-optical systems feeding a single radiating aperture generate orthogonal beams with a low crossover level between adjacent beams (around −13 dB at most). To circumvent this limitation, we present a circuit architec
