Fabrication and Modeling of Matching System for Air-Coupled Transducer

Fabrication and Modeling of Matching System for Air-Coupled Transducer

The tremendous acoustic impedance difference between the piezoelectric composite and air prevents the ultrasonic transition, resulting in low amplitude for the received signal for the composite defect detection using an air-coupled transducer. The matching system, which includes the matching layers...
