Abstract :
Acoustic impedance matching of ultrasonic transducers is studied theoretically. The theory is based on the fundamentals of acoustic transmission and can be used to predict the properties of matching layers more conveniently and completely. The authors examine the variation of the properties with frequency as well as the thicknesses, number, and characteristic acoustic impedances of matching layers.<>
