Radiation impedance of an array of circular capacitive micromachined ultrasonic transducers [PDF]

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2010
The radiation impedance of a capacitive micromachined ultrasonic transducer (cMUT) with a circular membrane is calculated analytically using its velocity profile for the frequencies up to its parallel resonance frequency for both the immersion and the airborne applications. The results are verified by finite element simulations. The work is extended to
