Abstract
Ultrasonic surface waves above a layer indented by a doubly periodic set of holes having a square-shaped cross section are studied experimentally. Mea surements are compared with predictions obtained from a modal model inspire d by the theory of the diffraction of electromagnetic waves. Predictions ob tained with the modal model and a simplified model where the periodic struc ture is replaced by an impedance plane are compared.
