    • Microfabricated ultrasonic transducers: towards robust models and immersion devices 

      Ladabaum, I.; Jin, X.; Soh, H. T.; Pierre, F.; Atalar, Abdullah; Khuri-Yakub, B. T. (IEEE, 1996-11)
      The successful fabrication of ultrasonic immersion transducers is reported. Transducers are observed to operate from 1 MHz to 20 MHz in water, with the frequency range limited by electronics, not the transducers. Transmission ...
    • Micromachinable leaky wave air transducers 

      Degertekin, F. L.; Atalar, Abdullah; Khuri-Yakub, B. T. (IEEE, 1997-11)
      In this paper, ultrasonic air transducers which use the lowest order antisymmetric (A/sub 0/) mode Lamb waves in a thin plate as a means of efficient coupling of ultrasonic energy to air are discussed. For a silicon plate ...
