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 ... -
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 ... -
Numerical optimization of ultrasound transducers by the linearity of the phase spectrum
Andersen, Kenneth Kirkeng; Frijlink, Martijn Egbert; Hoff, Lars (Journal article; Peer reviewed, 2017)New ultrasound imaging and therapeutic modalities may require transducer designs that are not easily facilitated by conventional design guidelines and analytical expressions. This motivates the investigation of numerical ... -
Therapeutic dual-frequency ultrasound transducers
Andersen, Kenneth Kirkeng (Doctoral thesis, 2020)The interaction of ultrasound with organic and non-organic matter has opened up for a vast industry. Arguably, in medicine, the most known application of ultrasound is diagnostic imaging of fetuses. However, ultrasound can ...
