Plots of reflection coefficient, as a function of branch to trunk area ratios for six arterial diameters a branch to trunk stiffness ratio = 0.9 (i.e., the branch artery are softer than the trunk artery, and b branch to trunk stiffness ratio = 1.1 (i.e., the branch arteries are stiffer than the trunk)
