Forward problem for Love and quasi Rayleigh waves: Exact dispersion relations and their sensitivities
We examine two types of guided waves: the Love and the quasi Rayleigh waves. Both waves propagate in the same model of an elastic isotropic layer above an elastic isotropic halfspace. From their dispersion relations, we calculate their speeds as functions of the elasticity parameters, mass densities, frequency and layer thickness. We examine the sensitivity of these relations to the model and wave properties.
