Abstract
We present our recent experimental results of the mutual radiation impedance of piezoelectric cylindrical shell transducers in arrays using the Z- and V-methods previously reported by the authors [J. Acoust. Soc. Am. 112, 2407 (2002)]. The mutual radiation impedance in an array of two coaxially aligned cylindrical transducers was determined as a function of separation distance. The results obtained by both methods are in good agreement with the calculations based on the analytical equations for a similar array developed by D. H. Robey [J. Acoust. Soc. Am. 27, 706–710 (1955)]. The mutual radiation impedances in other array geometries including planar and curved arrays of cylindrical shell transducers, in which there is no known analytical solution, were also measured by the same methods in our underwater test facility.
