Abstract :
The equivalent circuits for high-frequency transducers with quarter-wave matching layers, such as are used in sonar and ultrasonic applications, are discussed in terms of simple lumped bandpass filter circuits. Expressions for the matching criteria are given for half-section and full-section filters.
