    • Characterization of layered materials by the Lamb wave lens 

      Atalar, Abdullah; Koymen, H.; Degertekin, L. (IEEE, 1990)
      The Lamb wave lens is a type of lens that can replace the conventional lens of an acoustic microscope for some applications. When it insonifies a layered solid structure, it excites a single mode in the structure, provided ...
    • High efficiency Lamb wave lens for subsurface imaging 

      Atalar, Abdullah; Koymen, H. (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 ...
