    • Designing efficient CMUT cells for airborne applications 

      Unlugedik, A.; Tasdelen, A. S.; Atalar, Abdullah; Koymen, H. (IEEE Computer Society, 2014)
      In this work, we study airborne CMUT cells with vacuum gap where silicon plate is operated both in elastically linear and nonlinear regimes. We report the results of a new mode of operation where the plate center swings ...
    • Designing transmitting CMUT cells for airborne applications 

      Ünlügedik, A.; Taşdelen, A.; Atalar, Abdullah; Köymen, H. (Institute of Electrical and Electronics Engineers Inc., 2014)
      We report a new mode of airborne operation for capacitive micromachined ultrasonic transducers (CMUT), in which the plate motion spans the entire gap without collapsing and the transducer is driven by a sinusoidal voltage ...
    • 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 ...
    • Stagger tuned cMUT array for wideband airborne applications 

      Olcum, S.; Atalar, Abdullah; Köymen H.; Senlik, M.N. (2006)
      In this study, we explore the limits of cMUTs in air-borne applications. First we investigate the ways of increasing the bandwidth of a single cMUT cell in air. The effect of array operation is also considered in order to ...
