In this contribution a way to associate quasi-particles in inertial or non-inertial motion with surface-wave solutions is shown, especially for Rayleigh and Bleustein-Gulyaev surface waves on elastic or piezoelectric substrates. Perturbations of various kinds are also envisaged. The technique employed for this is based on the exploitation of the wave-momentum equation deduced via Noether's theorem or by direct computation, and associated with the basic field equations.
