Wave propagation and reflection in the model of asymmetrically branching tree of elastic
cylindrical tubes filled with nonviscous fluid is considered when applied to pulse wave reflection in
arterial networks. Influence of the geometrical and mechanical properties of the network and vessel wall
on the pulse wave propagation and spectral properties of the total admittance of the network are
investigated.
It was found out that the admittance of the tree has a set of resonant harmonics. Any changes in
parameters of microcirculatory bed cause noticeable alterations of the amplitudes of resonant harmonics
and negligibly small alterations of other harmonics. The set of resonant harmonics is independent of some
variations in the tree geometry. These results substantiate a possibility of the pulse diagnosis of inner
organs state by observation the amplitudes of the resonant harmonics only without preliminary knowledge
of individual structure of real vascular bed of an inner organ.
