Figure 1. The reflection coefficients in the parent (\(\gamma_a\)) and major (\(\gamma_b\)) and minor (\(\gamma_c\)) daughter vessels as a function of the scale parameters \(\delta\) and \(\ u\). Noe the asymmetry of the reflection coefficients for wave fronts approaching the node in the different vessels. \(\gamma_a\) is predominantly positive and always the largest of the coefficients. \(\gamma_b\) and \(\gamma_c\) are always negative and \(\gamma_b\ge\gamma_c\).
