Abstract
The design of innovative wide-angle impedance matching (WAIM) structures is proposed to mitigate reflection issues arising when scanning waveguide-fed planar phased arrays. The WAIM is based on a metasurface which is composed by several unit cells arranged according to a triangular lattice. A System-by-Design (SbD) approach is exploited to synthesize - by means of a customized particle swarm optimization (PSO)-based algorithm - the geometrical descriptors of such a metasurface in order to reduce the reflections when steering the main beam of the array. Numerical results are shown in order to verify the effectiveness as well as the potentialities of the developed design strategy.
