    • Designing efficient CMUT cells for airborne applications 

      Ünlügedik, Aslı; Taşdelen, Akif Sinan; Atalar, Abdullah; Köymen, Hayrettin (IEEE, 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 ...
    • Electrically unbiased driven airborne capacitive micromachined ultrasonic transducer design 

      Ünlügedik, Aslı; Atalar, Abdullah; Kocabaş, Coşkun; Oğuz, H. Kağan; Köymen, Hayrettin (IEEE, 2012)
      We present a design method for airborne capacitive micromachined ultrasonic transducers (CMUT). We use an equivalent lumped element circuit to model both electrical and mechanical properties of CMUT and analyze it in ...
