实验研究了具有正方形截面的双周期孔洞压入层上的超声表面波。将测量结果与由电磁波绕射理论启发的模式模型所得到的预测进行了比较。将该模型与用阻抗平面代替周期结构的简化模型的预测结果进行了比较。
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.
