Abstract

The performance of a 2.3 MHz composite transducer with 1-3 connectivity is analyzed using the transmission line model. The basic transducer parameters, including the attenuation coefficient, are determined from the electrical impedance in the vicinity of the resonance. Using these parameters, the effects of internal losses on round trip insertion loss (RTIL) are investigated. Also, electrical impedance, pulse-echo, and RTIL response are calculated and found to be in good agreement with the experimental data.<>
