(a) Simulated distributions of the absolute pressure fields along the -bended interface with the frequency f = 401.8 Hz. (b) Simulated and experimental measured pressure amplitudes along the cutline labeled by red dashed line in (a). Black solid curve and red dotted curve represent the simulated and the experimental results, respectively. (c) Simulated distributions of the absolute pressure fields along the interface with two bends in a larger PnC.
