Abstract

In modern Rayleigh-wave devices, transducers are needed to generate Rayleigh waves in response to an applied electrical signal and to sense the waves so as to give an electrical output waveform. These are clearly key requirements for electronic devices, and are usually met by using interdigital transducers on piezoelectric substrates. The flexibility of modern fabrication techniques has enabled a very wide variety of transducer types to be developed, including for example apodised or chirped transeducers which perform signal processing operations in addition to transduction. In many cases the device response is determined mainly by the transducer behaviour, and a detailed understanding of the latter is therefore essential for both analysis and design of devices.
