(a) Top views of the sample with 90° intersection angle and six HR on each flanks. (b) Experimental facility. (c) Experimental and (d) simulated results of intensity patterns of a plane wave passing the sample in Fig. 6a. (e) Experimental and (f) simulated results of intensity patterns of a plane wave passing the sample without HR on each flanks.
