Abstract
An interdigital transducer (IDT) is one of the most essential components in surface acoustic wave (SAW) technology. The performance of the IDT is related to the propagation characteristics of SAWs on piezoelectric or non-piezoelectric substrates. In typical measurements of strain and acceleration, the construction of feedback loop delay-line oscillators is discussed for the use of SAWs on both a piezoelectric ceramic substrate and a layer structure consisting of a thin piezoelectric plate and fused quartz. The IDT can also operate as a transducer for radiating a longitudinal wave into water. The transducer performance for a solid—liquid boundary is discussed in terms of the real and imaginary velocities of leaky SAWs, the electromechanical coupling constant and the transducer efficiency for acoustic beam radiation into water. Practical C-mode acoustic imaging results are given for two types of transducer configurations.
