Figures

Image of FIG. 1.
FIG. 1.

(a) Schematic diagram of an orthogonal SAW device simulated in the current work. and denote (0, 22, 90) and (0, 22, 0) directions in the LGS substrate, respectively. (b) Calculated frequency response along (0, 22, 0) and (0, 22, 90) Euler directions in the simulated orthogonal SAW device.

Image of FIG. 2.
FIG. 2.

Contour plot showing (a) SH wave propagation along (0, 22, 90) direction on LGS substrate. Inset shows particle displacement profiles along the three principal directions for IDTs along the (0, 22, 90) direction. (b) Mixed mode wave propagation along the (0, 22, 0) direction on LGS substrate (scale bar in meters). Inset shows particle displacement profiles along the three principal directions for IDTs along (0, 22, 0) direction. The device is not drawn to scale.

Image of FIG. 3.
FIG. 3.

(a) Simulated fluid velocity vector profile for a peak input ac voltage of 2.5 V applied to the LGS SAW device operating at 68 MHz (scale bar is in m/s). (b) Streaming velocity profiles along the fluid film thickness computed by time averaging, for a peak input ac voltage of 2.5 V applied to the LGS SAW device operating at 68 MHz.
