    • Constitutive Equations of Piezoelectric Layered Beams with Interdigitated Electrodes 

      Nguyen, Cuong Hung; Hanke, Ulrik; Halvorsen, Einar (Peer reviewed; Journal article, 2018)
      This paper establishes the constitutive equations, or linear two-port models, of piezoelectric layered beams with interdigital electrodes (IDEs). The effect of the nontrivial field on the transduction is analyzed. Based ...

    • Nonlinearity in a medical ultrasound probe under high excitation voltage 

      Huynh, Thong; Haugen, Geir Ultveit; Eggen, Trym Haakon; Hoff, Lars (Peer reviewed; Journal article, 2020)
      Tissue harmonic imaging is often the preferred ultrasound imaging modality due to its ability to suppress reverberations. The method requires good control of the transmit stage of the ultrasound scanner, as harmonics in ...
