Abstract
A surface acoustic wave device comprises a transducer 1 consisting of two electrodes 2 and 3 deposited on the surface of a substrate 4. Transducer 1 is a slanted chirped transducer with short fingers 5 and 6 to focus any acoustic wave generated in the transducer to a position along a line 8 spaced from transducer dependent on the frequency of the signal.
