    • A novel equivalent circuit model for CMUTs 

      Oğuz, H. Kağan; Olcum, Selim; Senlik, Muhammed N.; Atalar, Abdullah; Köymen, Hayrettin (IEEE, 2009-09)
      A nonlinear equivalent circuit for immersed transmitting capacitive micromachined ultrasonic transducers (CMUTs) is presented. The velocity profile across the CMUT surface maintains the same form over a wide frequency ...
    • Radiation impedance of collapsed capacitive micromachined ultrasonic transducers 

      Ozgurluk, A.; Atalar, Abdullah; Köymen, Hayrettin; Olçum, S. (Institute of Electrical and Electronics Engineers, 2012)
      The radiation impedance of a capacitive micromachined ultrasonic transducer (CMUT) array is a critical parameter to achieve high performance. In this paper, we present a calculation of the radiation impedance of collapsed, ...
