Abstract :
A theoretical analysis of 1-3 composites is shown to predict coupling and velocity values which agree reasonably well with experimental data. The measured properties of 1-3 composites are used to predict single element transducer performance with the KLM model. The modeled waveform and spectra agree well with experimentally measured transducers. For an air backed transducer, an insertion loss of 7.0 dB and a bandwidth of 97% is shown for a single crystal composite single element transducer
