In the design of transducers for bulk wave a-o devices, the thickness resonance frequency f0 is always taken as working frequency. By analysing and determining several characteristic frequencies for a transducer, it is pointed out that the mechanical resonance frequency f, must be taken as the working frequency, and a method for detemining tfs from the relationship graph on Smith chart between impedance and frequency of a transducer is proposed.
