    • Design and implementation of capacitive micromachined ultrasonic transducers for high power 

      Yamaner F.Y.; Olcum, S.; Bozkurt, A.; Köymen H.; Atalar, Abdullah (2011)
      Capacitive micromachined ultrasonic transducers (CMUTs) have a strong potential to compete piezoelectric transducers in high power applications. In a CMUT, obtaining high port pressure competes with high particle velocity: ...
    • 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 ...
    • An equivalent circuit model for transmitting capacitive micromachined ultrasonic transducers in collapse mode 

      Olcum, S.; Yamaner, F. Y.; Bozkurt, A.; Köymen, H.; Atalar, Abdullah (IEEE, 2011)
      The collapse mode of operation of capacitive micromachined ultrasonic transducers (CMUTs) was shown to be a very effective way to achieve high output pressures. However, no accurate analytical or equivalent circuit model ...
    • Optimizing CMUT geometry for high power 

      Yamaner F.Y.; Olcum, S.; Bozkurt, A.; Koymen H.; Atalar, Abdullah (2010)
      Capacitive micromachined ultrasonic transducers (CMUTs) have demonstratedvarious advantages over piezoelectric transducers. However, current CMUT designsproduce low output pressures with high harmonic distortions. Optimizing ...
