Characterization of Air-Coupled Transducers

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 1996
This paper describes a theoretical and experimental study for determination of the through-air system impulse response and insertion loss with different air-coupled ultrasonic transducers. Wide-band piezopolymer transducers (PVDF) are employed in both transmission and reception modes and their behavior assessed by means of mathematical modeling and ...
