Phase velocity measurements versus frequency for the polycarbonate slab (25.8 mm thickness). Measurements were performed with 500 kHz (circles) and 1 MHz (x’s) broadband transducers. The error bars denote standard deviations for measurements. Measurements reported by Droin, Berger, and Laugier (1998, squares) are also shown (30 mm polycarbonate cylinder).
