    • Bandwidth improvement in a cMUT array with mixed sized elements 

      Bayram, Can; Olcum, Selim; Şenlik, Muhammed N.; Atalar, Abdullah (IEEE, 2005-09)
      A capacitive micromachined ultrasonic transducer (cMUT) is typically fabricated by concatenation of several cMUT cells with identical physical dimensions. If the membrane thickness is kept fixed, the radius of the cMUT ...
    • Bilateral CMUT cells and arrays: equivalent circuits, diffraction constants, and substrate impedance 

      Köymen, Hayrettin; Atalar, Abdullah; Taşdelen, A. S. (Institute of Electrical and Electronics Engineers Inc., 2017)
      We introduce the large-signal and small-signal equivalent circuit models for a capacitive micromachined ultrasonic transducer (CMUT) cell, which has radiating plates on both sides. We present the diffraction coefficient ...
