Measuring of the Thickness of Thin Films with the Use of Harmonic Antisymmetric Lamb Waves

  • Kh. B. TolipovEmail author

We propose a method for measuring the micrometer-range thicknesses of thin films with the use of acoustic waves. The method is based on the use of the nonlinear dependence of antisymmetric harmonic Lamb waves on the thickness of the tested material. The errors of measurements of the thickness of thin films are analyzed with the help of a contactless electromagnetoacoustic transducer of acoustic waves.
