N2 - We present an analytical scheme for the design of wide-angle metagrating (MG) diffusers, featuring a sparse periodic arrangement of polarizable particles (meta-atoms) embedded in a realistic fabrication-ready printed circuit board (PCB) configuration. Based on the Floquet-Bloch theorem, we model the MG as a multiport network, and design the meta-atom constellation and geometry to evenly spread the impinging power among numerous scattered waves in different directions, while specifically suppressing retroreflection. By enforcing multiple constraints simultaneously, we show that as little as three meta-atoms per period are sufficient to obtain this response over a broad angular range, thus offering an innovative solution to monostatic and bistatic radar cross section (RCS) reduction.
