2D STPC matrices of dimension 16 × 4 capable of generating the (a) 0°-, (b) 45°-, and (c) 90°-polarized reflection wave, where distinct colored blocks represented different phase coding. The measured normalized far-field scattering patterns of (d) 0°-, (e) 45°-, and (f) 90°-polarized reflection waves at the 0th-, +1st- and -3rd-order harmonics. The polarization is defined in the plane orthogonal to the propagating direction of the beam
