The radial vibration of a radial composite tubular transducer with a large radiation range and power capacity is studied. The transducer is composed of a longitudinally polarized piezoelectric ceramic tube and a coaxial outer metal tube. Assuming that the longitudinal length is much larger than the radius. the electromechanical equivalent circuits of the radial vibration of a piezoele... https://www.soiebiologique.com/limited-price-Test-Evaluation-Command-ACU-Patch-Foliage-Green-flash-choice/
