本工作利用特殊设计的声子晶体结构实现了单边波的传输。它是一种倒置双棱镜声子晶体，用于在特定频率水平入射弹性波。实验表明，沿一个方向的入射波被双棱镜完全反射，而沿相反方向的入射波则以折射的方式穿过双棱镜。所提出的双棱镜可以在弹性薄带中找到应用。(C)2012年美国物理研究所。[http://dx.doi.org/10.1063/1.4721485]
This work presents the realization of one-sided wave transmission by using a specially engineered phononic crystal structure. It is an inverted bi-prism phononic crystal engineered for a horizontally incident elastic wave at a specific frequency. The incident wave along one direction is shown to be totally reflected by the bi-prism while the incident wave along the opposite direction transmitted through it with refraction, also evident from experiments. An application of the proposed bi-prism may be found in thin elastic strips. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4721485]
