    • CMUT array element in deep-collapse mode 

      Olcum, S.; Yamaner F.Y.; Bozkurt, A.; Köymen H.; Atalar, Abdullah (2011)
      Collapse and deep-collapse mode of operations have boosted the pressure outputs of capacitive micromachined ultrasonic transducers (CMUTs) considerably. In this work, we demonstrate a CMUT element operating in the deep-collapse ...
    • Design and implementation of capacitive micromachined ultrasonic transducers for high power 

      Yamaner F.Y.; Olcum, S.; Bozkurt, A.; Köymen H.; Atalar, Abdullah (2011)
      Capacitive micromachined ultrasonic transducers (CMUTs) have a strong potential to compete piezoelectric transducers in high power applications. In a CMUT, obtaining high port pressure competes with high particle velocity: ...
    • Optimization of linear wire antenna arrays to increase MIMO capacity using swarm intelligence 

      Olgun, U.; Tunc, C.A.; Aktas, D.; Erturk V.B.; Altintas, A. (2007)
      Free standing linear arrays (FSLA) are analyzed and optimized to increase MIMO capacity. A MIMO channel model based on electric fields is used. The effects of mutual interactions among the array elements are included into ...
    • An overview of research in 3DTV 

      Onural, L. (2007)
      3DTV is regarded by the experts and the general public as the next major step in video technologies. The ghost-like images of remote persons or objects are already depicted in many futuristic movies; both entertainment ...
    • Radiation impedance and equivalent circuit for immersed CMUT array element 

      Senlik, M.N.; Atalar, Abdullah; Koymen H.; Olcum, S. (2006)
      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 ...
    • Simulation of a digital communication system 

      Güngör, A.; Arikan F.; Arikan, O. (2005)
      In this paper, basic components of a digital communication system are simulated by a computer program. The simulation program is modular and flexible to incorporate any future additions and updates. The simulation program ...
