The signal response of a two-dimensional elastic coating attached to a submerged plate has been examined. The coating response was generated by an incident acoustic plane wave impinging on the surface. The main points of interest were the normal and tangential velocity components of the coating response as functions of frequency, signal arrival angle, location through the coating thickness, and coating parameters. Primary attention was focused on developing physical understanding of the processes affecting the coating response, and the mechanisms by which this response could be tailored to achieve desired results. The waveguide behavior of the coating was found to be useful in explaining the signal response. In particular, it was found that the dilatational resonances were useful in explaining the normal velocity response, while the shear resonances were found to be associated with the tangential velocity maxima.
