The Rayleigh wave propagation problem in the elastic substrate-viscoelastic layer interface was analysed in the paper. The fundamental solution of the problem has been found in the Fourier-Laplace space using Biot viscoelastic solid model with Maxwell relaxation time. The space time form: of the solution was obtained using Cagniard-deHoop method. The solution presented in the paper seems to be applicable to surface acoustic waves gas sensors with polymeric (viscoelastic) layer.
