Acoustic Impedance Matching of PMN-PT/epoxy 1-3 Composites for Underwater Transducers with Usable Bandwidth Restricted by Electrical Power Factor
Røed, Ellen Katrine Sagaas; Andersen, Kenneth Kirkeng; Bring, Martin; Tichy, Frank; Åsjord, Else-Marie; Hoff, Lars (Peer reviewed; Journal article, 2019)Volume cost has limited the use of single crystals in underwater applications, butreported performance of PMN-PT sonar transducers now motivates the design of commercial prototypes. This work addresses optimization of the ... -
Electrical power factor for a single crystal tonpilz versus a plate with matching layers
Røed, Ellen Katrine Sagaas; Bring, Martin; Tichy, Frank; Åsjord, Else-Marie; Hoff, Lars (Peer reviewed; Journal article, 2021)For underwater transducers mounted on small platforms, reactive electrical power can constitute a main restriction on the usable frequency range. The frequency range in which the amount of reactive power is acceptable can ... -
Heat generation in underwater transducers
Wild, Marcus Sebastian (Doctoral dissertations at the University of South-Eastern Norway;38, Doctoral thesis, 2019)Acoustic transducers are used for a variety of applications, ranging from medical to maritime uses. In the maritime sector, underwater transducers can be used for appli- cations such as seabed mapping, fishing and ... -
Increased Usable Frequency Band for Underwater Transducers with Single Crystal
Røed, Ellen Katrine Sagaas; Andersen, Kenneth Kirkeng; Bring, Martin; Tichy, Frank; Åsjord, Else-Marie; Hoff, Lars (Peer reviewed; Journal article, 2020)In the increasing market of transducers for small underwater platforms, each transducer should be used for several purposes, hence cover as large frequency range as possible. Bandwidth is commonly defined as the -3dB limit ...
