Abstract

In the Kirchhoff approximation, the acoustic path of a normal transducer with a rectangular piezoelectric plate is calculated for reflectors of the type of rectangular and circular flat-bottom holes. The formula for the acoustic path can be used for constructing DGS diagrams. In limiting cases, relationships coinciding with familiar ones follow from this formula for the acoustic path. Numerical calculations of DGS diagrams of a transducer with a rectangular piezoelectric plate with different ratios of sides are performed and certain features are pointed out. Additional results of numerical calculations of a bottom signal of such a transducer performed with the relation obtained above are presented.
