Rayleigh wave manipulation based on phase shift between two periodic surface corrugations Open
The propagation of Rayleigh waves along solid surfaces has attracted great attention due to its ubiquity in seismic waves, non-destructive evaluation, acoustic surface wave devices, and so on. Moreover, Rayleigh waves in periodic structure…

Temperature tuning of defect state induced by the periodic cavities between the phononic crystals Open
The defect state in periodic structures usually leads to a pass band in the forbidden bandgap and energy localization at the position of geometric change. In this paper, we have introduced periodic cavities into a symmetric structure compo…
