Visualization 8: The normalized acoustic pressure distribution when the wavelength of incident acoustic Gaussian beam changes from λ0/3 to 2λ0 (λ0 is designed working wavelength that satisfies Fabry-Pérot condition). Acoustic Gaussian beam normally incidents onto the multi-physics scattering reduction device in Fig. 4(a) (other settings keep the same as these in Fig. 4).
