摘要：
Ultrasonic surface waves above a layer indented by a doubly periodic set of holes having a square-shaped cross section are studied experimentally. Measurements are compared with predictions obtained from a modal model inspired by the theory of the diffraction of electromagnetic waves. Predictions obtained with the modal model and a simplified model where the periodic structure is replaced by an impedance plane are compared.
