Simulation results: Total displacement in the substrate for the SAW resonator with SU-8 pillars of height (a) h = 0 μm (no pillar), (b) h = 10 μm, (c) h = 12 μm, (d) h = 23 μm, (e) h = 34 μm, and (f) h = 36 μm. The resonance mode of the pillar of different heights can be observed from the total displacement profile and deformation pattern of the pillars. For simplicity substrate depth up to 2λ along x3 is shown. In order to have a better visualization, the original deformation value is magnified 100 times and shown in the figure.
