A reciprocity relation for fluid loaded elastic plates that contain rigid defects

A reciprocity relation between the far-field behaviour of the scattered fields generated by incident waves, either flexural plate waves, or incident from the fluid, upon rigid defects embedded in a thin elastic, fluid-loaded, plate is derived. This reciprocity result is then illustrated upon model problems for which the explicit solution can be determined and the relation demonstrated.
