(a) Geometry of acoustic goniometer. and are the large-aperture transmitter and the small receiver, respectively, mounted along the specular reflection path with angle of incidence . (b) Illustration of change in the bounded pulse amplitude profile upon nonspecular reflection near the Rayleigh critical angle (after Ref. 17). (c) Photograph of experimental configuration.

FIG. 2.

(a) Illustrative comparison of the plane wave reflectivity with that modeled along the specular path for a water-loaded copper interface vs angle of incidence . (b) The accompanying phase rotations upon reflection vs .

FIG. 3.

Left panels (a)–(c): Snapshot frames of the propagating bounded pulse incident at the precritical angle [full animation available in online supplementary material (Ref. 36)], respectively. (d)–(f) Snapshot frames of the propagating bounded pulse incident at the Rayleigh critical angle [full animation available in online supplementary material (Ref. 36)], respectively. Note that the amplitudes are displayed as the modulus of the analytic signal (i.e., the positive valued amplitude envelope).
