Abstract
The surface wave dispersion for a barrier oxide film on aluminium has been determined from surface Brillouin scattering measurements carried out on fi lms of thicknesses of 0.2, 0.35 and 0.45 mu m. The measured Velocities of t he generalised Rayleigh mode, the pseudo interfacial mode and of several La mb modes conform to simulations performed for stiffening layers [1]. The lo ngitudinal velocity and the shear Velocity of the layer have been calculate d from the experimental dispersion curve. (C) 1999 Elsevier Science S.A. Al l rights reserved.
