【 摘 要 】

Problem statement: Love waves or shear waves are referred to dispersive SH waves. Thediffusive parameters are found to produce complex amplitude and diffusive waves for energy hauling.Approach: Analytical solutions are found for analysis and discussions. Results: When the standingwaves are compared with the Love waves, similar cosine component is found in both waves. Energyhauling between waves is impossible for Love waves if the cosine component is independent. In theview of 3D particle motion, the sine component of the Rayleigh waves will interfere with shear wavesand thus the energy hauling capability of shear waves are formed for generating directed dislocations.Nevertheless, the cnoidal waves with low elliptic parameter are shown to act analogous to Rayleighwaves. Conclusion: Love waves or Rayleigh waves are unable to propagate energy once the sinecomponent does not exist.
