FIG. 2.
Numerical simulations of wave propagation through the acoustofluidic device. Plots of the normalized velocity waves (v/v0) are shown for (a) kwW = π, (b) kwW = 0.9π, and (c) kwW = 1.1π. Plots of the normalized pressure waves (p/P0) are shown for (d) kwW = π, (e) kwW = 0.9π, and (f) kwW = 1.1π. The grey regions of the waves indicate calculated values in the silicon domains, the blue regions of the waves indicate calculated values in the fluidic domain, and the dashed lines represent the boundaries between domains. Note: the incoming wave enters from the left-hand side and travels to the right in this simulation.
