    • 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 ...
    • 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 ...
