摘要：
For a direct transducer with a circular piezoelectric plate, a comparative analysis of acoustic field calculations by the Helmholtz-Huygens and Fourier-Bessel formulas is performed. The equivalence of these calculations is demonstrated. A refined expression is obtained for the pressure on the transducer axis as a function of distance. The field calculations are also performed for square and triangular piezoelectric plates. A comparison of numerical results is carried out.
