之前已经在低频下研究了链状材料中的波传播。目前的研究已经产生了这些波在较高的频率与组件>200千赫，使用链的1毫米直径的球体。在73 kHz的谐振超声喇叭已被用作窄带激励源，它转换成一列宽带脉冲，具有孤立波的特性。这些脉冲在生物医学超声中具有潜在的应用，如高振幅，宽带宽脉冲。
Wave propagation in chain-like materials has been studied previously at low frequencies. The present study has generated these waves at higher frequencies with components >200 kHz, using chains of 1 mm diameter spheres. Resonant ultrasonic horns at 73 kHz have been used as sources of narrowband excitation, which transform into a train of broadband impulses that have the characteristics of solitary waves. These have potential applications in biomedical ultrasound as high amplitude, wide bandwidth impulses.
