    • An equivalent circuit for collapse operation mode of CMUTs 

      Olcum, S.; Yamaner F.Y.; Bozkurt, A.; Koymen H.; Atalar, Abdullah (2010)
      Collapse mode of operation of the capacitive mi-cromachined ultrasonic transducers (CMUTs) was shown to be a very effective way for achieving high output pressures. However, no accurate model exists for understanding the ...
    • Finite element modeling of micro-particle separation using ultrasonic standing waves 

      Büyükkoçak, S.; Çetin, B.; Özer, M. B. (Web Portal ASME (American Society of Mechanical Engineers), 2014)
      Acoustophoresis which means separation of particles and cells using acoustic waves is becoming an intensive research subject. The method is based on inducing an ultrasonic compression standing wave inside a microchannel. ...
    • 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 ...
