Figure 3

Comparison of numerical dispersion relation and experimental transmission results along different crystallographic directions (samples with l = 5.0 mm and A = 1.0 mm). (a) Numerical dispersion relation (d = 0.52 mm) with complete band gaps indicated in grey. (b) Experimental transmission spectrum of a sample with transmission direction (100), (c) (110) and (d) (111) with a thickness of 0.52 mm 0.08 mm.
