Capacitive micromachined ultrasonic transducers (CMUTs) manufactured on silicon substrates need an acoustic backing to suppress substrate ringing when such transducers are in operation. The acoustic backing most often used for ultrasound transducers

Capacitive micromachined ultrasonic transducer (CMUT) has been emerging technology in the field of medical imaging after its first demonstration in early 90s. CMUTs are fabricated on silicon substrates using micromachining techniques. They can genera

2009 IEEE International Ultrasonics Symposium.
Capacitive Micro-machined Ultrasonic Transducer (CMUT) transducers need an acoustic backing to ensure that any acoustic signal which propagates from the transducer into the substrate is absorbed in the backing. The backing should be made such that it
