Rayleigh wave dispersion
WebApr 11, 2024 · Examples of calculations of the root of the generalized Rayleigh equation N (α) = 0 are shown in Fig. 2. Here we show the dispersion relations in terms of prescribed frequency of the process ω and the evaluated root α 0 (Fig. 2 a). Corresponding values of the Rayleigh waves phase velocity c g r = ω / α 0 are presented in Fig. 2 b.
