Abstract : The patent describes a set of interdigitated surface wave transducers comprising a launch transducer which transmits an acoustic wave in one direction only, rather than the usual two opposite directions, and a receiving transducer which receives an acoustic signal from one direction only, the direction from the launch transducer. An auxiliary delay line may also be used. The set of transducers may be configured in any of three different arrangements.
