= Anisotropic Love-wave dispersion
{title2=$\tan(qh)=\mu\kappa/(\rho'\beta_z'^2q)$}
For an aligned anisotropic surface layer, $q^2=(\omega^2-\beta_x'^2k^2)/\beta_z'^2$, while the isotropic substrate has $\kappa^2=k^2-\omega^2/\beta^2$. Zero top <traction> and welded displacement/traction continuity give the displayed <dispersion relation>. The horizontal speed sets the limiting <phase velocity>; the vertical speed sets rigid-base cutoff frequencies. The effective contrast for the high-contrast transition is $\rho'\beta_x'\beta_z'/(\rho\beta^2)$.
