This happens in Acoustic plate-mode (Apm) oscillators, which have a thickness of only a few microns. The eigenfrequency of the Apm oscillators is given by the interdigitated electrode spacing p and by the plate thickness t. [Pg.91]

Plate-Mode Oscillators (PMOs). Lamb Wave Oscillators. In all the SAW devices discussed above, the acoustic wave propagates in a slab of material whose thickness is infinitely larger than the wavelength A of the propagating wave. When the thickness of the plate is reduced to such an extent that it becomes comparable to A, the entire plate becomes involved in the periodic motion, producing a symmetric and antisymmetric Lamb wave (LW) (Fig. 49). This behavior is observed in plate-mode oscillators with thicknesses of a few micrometers. A cross-sectional view through a typical PMO is shown in Figure 50. [Pg.1011]
