Abstract
The attenuation of Rayleigh waves due to their interaction with resonating structures randomly distributed on the surface of a semi-infinite elastic m edium is calculated along with the Rayleigh wave frequency. The resonating structures are modeled by single oscillators coupled to the displacement fi eld at the surface of the elastic medium. Using the coherent potential appr oximation, the dependence of the frequency and damping constant of the Rayl eigh waves on wave vectors are determined for various values of the concent ration of oscillators on the surface.
