Measurement of beam focusing and beam steering performance.
(a) Measured 3-dimensional focused beam. (b) Measured and simulated focused beams pointed at (0°, 0°). (c) Measured steering beams in xoz plane. The corresponding coding matrices and the simulated results are presented in Fig. 6(b–d), respectively.
