    • 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 ...
    • New directional acoustic lens: V-groove lens 

      Bozkurt, A.; Yarahoglu, G.; Atalar, Abdullah; Koymen, H. (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 ...
    • Synthetic aperture imaging system using surface wave modes 

      Bozkurt, A.; Arikan, O.; 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 ...
