Radiation conductance of apodized ID transducers in wedges

摘要

The radiation conductance of an apodized ID transducer for acoustic waves in wedges is derived from normal‐mode theory. Using the analytical expressions for the field distribution developed in an earlier paper, the radiation conductance is calculated for an ID transducer on a 40° LiNbO3 wedge. The calculated values are in good agreement with published experimental results.
