摘要：

In order to understand the mechanism of two longitudinal wave propagation phenomena in the cancellous bone, we have tried to investigate the wave separation in the bone specimen by changing the main frequency of the longitudinal pulse wave. Here, we have used the specimens obtained from the end of bovine femur, which are covered by cartilage and subcondral bone. The pore size changed gradually in the specimens. We have then found the effect of the structure on the wave separation. The FDTD simulation with the CT image of the specimens showed similar behavior of wave propagation.
