摘要:

Measurements and calculations have shown tourmaline to be a useful surface‐acoustic‐wave‐delay medium. In particular, its combination of high velocity and very low propagation losses, together with a moderate piezoelectric coupling strength, makes it suitable for use at higher frequencies than are feasible with quartz or LiNbO3.
