Table 4 Two-layered media with different impedance ratios and cap-layered media (V _p = 2V _s, density = 2.0 g/cm³)

From: Application of a simplified calculation for full-wave microtremor H/V spectral ratio based on the diffuse field approximation to identify underground velocity structures

Layer	V _s						Depth
1	V _s1 = 100 m/s						10 m(= λ ₀/4)
2	2V _s1	4V _s1	5V _s1	6V _s1	7V _s1	8V _s1	400 m(= 10λ ₀)^a
Cap	4V _s1	8V _s1	10V _s1	12V _s1	14V _s1	16V _s1	∞

^aThe thickness of second layer is infinite for two-layered medium
