A low frequency torsional transducer for the generation and/or reception of shear waves in a substantially solid medium. The transducer includes a spool like radiating structure to which are fixedly attached spaced piezoelectric elements. The element

Two cylindrical, high‐gain, wide‐band (three octaves) passive arrays have been recently developed. Both arrays consist of 36 lead titanate elements mounted on a cylindrical structure. The elements are arranged in a 3×12 configuration with the 12

The purpose of this study was to determine the effects of encapsulation methods on the acoustic performance of a passive, cylindrical, high gain, broadband (multi‐octave) array. Both an oil‐filled boot and a polyurethane coating were considered.

Based on a previous design of a low‐frequency, torsional shear wave transducer [A. K. Walden and T. R. Howarth, J. Acoust. Soc. Am. 91, 2463 (1992)], an analytical model is proposed to predict the radiated acoustic field. The stress and displacemen
