The problem of Rayleigh surface wave transmission and reflection by stripes of viscous liquid is considered using a Maxwellian model of viscosity characterized by a single relaxation time. The aim is to interpret experiments on surface acoustic wave monitoring of the wetting of high-energy solid surfaces. These experiments demonstrated a strong oscillatory behaviour of both transmission and reflection coefficients as the area occupied by the liquid increased with time. The variable thickness of the liquid is taken into account and analytical results and numerical calculations are presented.
