N2 - We report the design, fabrication, and experimental characterization of a printed circuit board metagrating (MG)for perfect anomalous reflection. The periodic structure, comprised of a single element per period, was synthesized following our previously developed analytical formalism to guarantee unitary coupling to the desirable Floquet-Bloch (FB)mode, while suppressing specular reflections entirely. The experimental setup allows a bistatic measurement of the MG radiation pattern, enabling evaluation of the scattering to the different FB modes, without requiring a reference measurement with a metallic plate. The results verify our theoretical predictions, indicating that highly-efficient anomalous reflection to the prescribed angle is achieved, thus demonstrating the practical applicability of MGs for future wavefront manipulating devices.
