    • Acoustical tuning of CMUT receiver arrays 

      Taşdelen, Akif Sinan; Atalar, Abdullah; Enhoş, Kerem; Köymen, Hayrettin (IEEE, 2016)
      Cell placement in an element and structural modifications on the array baffle significantly change the bandwidth, band shape and signal to noise ratio of a CMUT receiver array. In this paper, optimum receiver performance ...
    • Radiation impedance of an array of circular capacitive micromachined ultrasonic transducers in collapsed state 

      Özgürlük, Alper; Atalar, Abdullah; Köymen, Hayrettin; Olcum, Selim (IEEE, 2011-10)
      Radiation impedance is one of the important parameters in designing efficient and wideband capacitive micro-machined ultrasonic transducer (CMUT) arrays. It determines how much acoustical power is generated in the surrounding ...
    • Radiation impedance of collapsed capacitive micromachined ultrasonic transducers 

      Ozgurluk, A.; Atalar, Abdullah; Köymen, H.; Olçum, S. (Institute of Electrical and Electronics Engineers, 2012)
      The radiation impedance of a capacitive micromachined ultrasonic transducer (CMUT) array is a critical parameter to achieve high performance. In this paper, we present a calculation of the radiation impedance of collapsed, ...
