    • Radiation impedance and equivalent circuit for immersed CMUT array element 

      Şenlik, Muhammed N.; Atalar, Abdullah; Köymen, Hayrettin; Olcum, Selim (IEEE, 2006-10)
      In this paper, we present equivalent circuit for immersed capacitive micromachined ultrasonic transducers (cMUT), based on an accurate parametric model. We also present an accurate approximation for the radiation impedance ...
    • Spectroscopic ellipsometric study of Ge nanocrystals embedded in SiO 2 using parametric models 

      Basa, P.; Petrik, P.; Fried, M.; Dâna, A.; Aydinli, A.; Foss, S.; Finstad, T. G. (Wiley - V C H Verlag GmbH & Co. KGaA, 2008)
      Ge-rich SiO2 layers on top of Si substrates were deposited using plasma enhanced chemical vapour deposition. Ge nanocrystals embedded in the SiO2 layers were formed by high temperature annealing. The samples were measured ...
