Abstract :
Ultrasonic probes which can simultaneously generate and receive 2 orthogonal polarized shear (S?? and S//) and longitudinal (L) waves in screw shape have been presented. Thick piezoelectric films are directly fabricated onto the heads of such probes as L wave integrated ultrasonic transducers. S?? and S// waves are obtained using mode conversion method. Potential applications of such probes are discussed.
