    • CMUT array element in deep-collapse mode 

      Olcum, Semih; Yamaner F.Y.; Bozkurt, A.; Köymen, Hayrettin; Atalar, Abdullah (IEEE, 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 ...
    • Deep-collapse operation of capacitive micromachined ultrasonic transducers 

      Olcum, S.; Yamaner F. Y.; Bozkurt, A.; Atalar, Abdullah (IEEE, 2011)
      Capacitive micromachined ultrasonic transducers (CMUTs) have been introduced as a promising technology for ultrasound imaging and therapeutic ultrasound applications which require high transmitted pressures for increased ...
    • Experimental verification of metamaterial based subwavelength microwave absorbers 

      Alici, K. B.; Bilotti, F.; Vegni, L.; Özbay, Ekmel (American Institute of Physics, 2010-10-29)
      We designed, implemented, and experimentally characterized electrically thin microwave absorbers by using the metamaterial concept. The absorbers consist of (i) a metal back plate and an artificial magnetic material layer; ...
