Abstract :
This paper is aimed at analyzing and discussing the key-role of the evolutionary optimization in EM device synthesis carried out within the recently developed System-by-Design paradigm. Towards this end, SbD models the design process as an eco-system of functional blocks (for the synthesis/analysis of each sub-part of the overall complex system) suitably connected to enable different trade-off solutions in terms of complexity, speed, effectiveness, and reliability. To give some insights on the role of EAs in the proposed methodology, the SbD Paradigm is here exploited in a specific design problem concerned with the synthesis of a wideband Wide-Angle Impedance Matching (WAIM) layer for improving the scanning performance of a phased array system.
