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

The objective of the experiments reported here has been to develop a fish tag, which is as cheap and simple to insert as the coded wire tag and which has the remote readout capabilities of the radio frequency (rf) based passive integrated transponder

A method for analyzing capacitive micromachined ultrasonic transducer (CMUT) arrays and arrays of elements composed of several CMUTs is proposed. It is based on a combination of a free acoustic mode description of an isolated CMUT, and the coupling o

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

The fact that CMUT transducers have not yet made it into commercial products indicates that so far the transducers does not meet the needs of the imaging community. This may be due to low sensitivity for the available arrays, a quality that is improv
