Abstract
In this work, the synthesis of metasurface-based wide-angle impedance matching (WAIM) layers is proposed. The designed structures allow to mitigate reflection issues in waveguide-fed planar phased arrays. To achieve such a goal, the synthesis problem is formulated in the System-by-Design (SbD) framework, and the degrees of freedom are represented by the geometrical descriptors of the metasurface unit cells. The final layout is then obtained by minimizing the antenna input reflections caused by impedance mismatching when the array is steered. A preliminary numerical validation is provided in order to assess the effectiveness and flexibility of the proposed SbD-based design approach.
