| Abstract(in English) | The propagation and resonance properties of a leaky SAW (LSAW) on bonded structures comprising of similar and dissimilar materials were investigated theoretically. A large positive temperature coefficient of frequency (TCF) for LSAW can be produced on a quartz thin plate bonded to a quartz substrate with a difference cut angle. We proposed a bonded structure comprising of a LiNbO3 (LN) thin plate and the quartz thin plate/quartz substrate, in which the negative TCF of the LN thin plate can be cancelled by the positive TCF. For the simulated resonance properties on the 64°YX-LN/Z30°X-quartz/ AT0°X-quartz, a similar fractional bandwidth to that of the single LN and near-zero TCF and were obtained simultaneously. |
