Flexural waves on a pinned semi-infinite thin elastic plate

The interaction of flexural waves with the edge of a thin semi-infinite elastic plate which is pinned at points along its edge is considered. In particular, it is shown how energy can be fed into edge waves when a plane incident wave is diffracted by points along the edge. Finally, we demonstrate the existence of a new type of Rayleigh–Bloch edge wave for a plate periodically pinned along its edge.
