a Photo of the sample. b Simulated acoustic pressure field distributions at 15.5 kHz for a point source (red star) on the left of the straight PC. c Experimentally measured dispersions (colors) compared to the simulated dispersions (white dots and red lines). d Experimental Fourier spectra (indicated by a color map) at a frequency of 15.5 kHz, as obtained by a Fourier transformation of the measured field distribution inside the domain delineated by the magenta dashed lines in b.
