We theoretically formulate and experimentally demonstrate an analytical formalism for designing printed circuit board (PCB) metagratings (MGs), exercising individual control over amplitude and phase of numerous diffracted modes, in both reflection and transmission. These sparse periodic arrangements of subwavelength polarizable particles (meta-atoms) are typically designed based on full-wave optimization of the meta-atoms, with scarce analytical schemes restricted to single-layer reflecting… Expand
