    • A novel equivalent circuit model for CMUTs 

      Oguz H.K.; Olcum, S.; Senlik, M.N.; Atalar, Abdullah; Köymen H. (2009)
      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 an array of circular capacitive micromachined ultrasonic transducers 

      Senlik, M. N.; Olcum, S.; Köymen, H.; Atalar, Abdullah (IEEE, 2010)
      The radiation impedance of a capacitive micromachined ultrasonic transducer (cMUT) with a circular membrane is calculated analytically using its velocity profile for the frequencies up to its parallel resonance frequency ...
    • Radiation impedance of collapsed capacitive micromachined ultrasonic transducers 

      Ozgurluk, A.; Atalar, Abdullah; Köymen, H.; 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, ...
