Comparison between FW H/Vs (thick black), SW H/Vs (gray), ellipticity of fundamental mode of Rayleigh waves (thin black) of two-layered media with six different impedance ratios, and SW H/Vs (red) of corresponding cap-layered media (in all cases V sCap = 2V s2, Depth = 10λ 0). As for the two-layered media, V s2 = 2V s1 in the upper left panel, V s2 = 4V s1 in the upper middle panel, V s2 = 5V s1 in the upper right panel, V s2 = 6V s1 in the lower left panel, V s2 = 7V s1 in the lower middle panel and V s2 = 8V s1 in the lower right panel
