    • Characterization and imaging with lamb wave lens at gigahertz frequencies 

      Bozkurt, Ayhan; Yaralıoğlu, Göksenin; Atalar, Abdullah; Köymen, Hayrettin; Kramer, K. (IEEE, 1994-10-11)
      Lamb wave lenses with conical refracting surfaces are fabricated for use at 400 MHz and 1 GHz. The conical surfaces are ground and polished with mechanical means and they are sufficiently smooth for the frequencies of ...

    • En acil sorun: korsan kitap 

      Bozkurt, Ayhan (1998)

    • Kaçışsız bir yaşam oyunu şiirleri 

      Bozkurt, Ayhan (1998)

    • Lens geometries for quantitative acoustic microscopy 

      Atalar, Abdullah; Köymen, Hayrettin; Bozkurt, Ayhan; Yaralıoğlu, Göksenin (Springer, 1995)
      The purpose of the first Lemons-Quate acoustic microscope(1) was to image the surfaces of materials or biological cells with a high resolution. Unfortunately, competition with the optical microscope was only partially ...

    • Modeling and characterization of capacitive micromachined ultrasonic transducers 

      Bozkurt, Ayhan (Bilkent University, 2000)
      The Capacitive Micromachined Ultrasonic Transducer (cMUT) is a device used for the generation and detection of ultrasonic sound waves. The device is constructed on a silicon substrate using a microfabrication process. ...

    • A new directional acoustic lens: V-groove lens 

      Bozkurt, Ayhan; Yaralıoğlu, G. Göksenin; Atalar, Abdullah; Köymen, Hayrettin (IEEE, 1993)
      A new directional acoustic lens is introduced. The geometry is very similar to the line-focus lens except the lens cavity, which is shaped as a groove with flat-bottom V cross section. The slanted planar edges of the groove ...

    • A synthetic aperture imaging system using surface wave modes 

      Bozkurt, Ayhan; Arıkan, Orhan; Atalar, Abdullah (IEEE, 1995)
      A synthetic aperture acoustic imaging system with a novel inversion algorithm is described. Data is obtained by using a transducer insonifying the sample surface at a critical angle which is excited by a short electrical ...

    • The V-Groove lens 

      Bozkurt, Ayhan (Bilkent University, 1994)
      Primarily designed for imaging purposes, the acoustic microscope finds application in the qualitative evaluation of materials, too. The lens response as a function of defocus, which is known as the V{z) curve, is formed ...
