    • Characterization and imaging of single layered materials by the Lamb wave lens 

      Değertekin, F. Levent (Bilkent University, 1991)
      The Lamb wave lens, which was introduced earlier as a new kind of lens for scanning acoustic microscope, is analyzed theoretically. A simulation program capable of handling single layered materials with different material ...
    • High efficiency Lamb wave lens for subsurface imaging 

      Atalar, Abdullah; Köymen, Hayrettin (IEEE, 1989-10)
      A conventional scanning acoustic microscope lens excites all the possible modes of acoustic waves in the solid structure under examination. The excited leaky modes contribute significantly to the high contrast obtained in ...
    • A Lamb Wave Lens for Acoustic Microscopy 

      Atalar, Abdullah; Köymen, Hayrettin; Değertekin, F. Levent (1992)
      In a conventional scanning acoustic microscope the excited leaky modes contributes significantly to the high contrast obtained in the images. However, all such modes exist simultaneously, and the interpretation of the ...
    • Material characterization by using high velocity modes 

      Yaralıoğlu, Göksen Göksenin (Bilkent University, 1994)
      Acoustic microscopy is one of the most powerful tools for non-destructive material characterization. Excited modes on the materials are responsible for the high contrast obtained in the images. However, conventional ...
