We study the isotropic elastic wave equation in a bounded domain with boundary coefficients having jumps at nested set of interfaces satisfying natural transmission conditions there. analyze detail microlocal behavior such solution like reflection, and mode conversion S P waves, evanescent modes, Rayleigh Stoneley waves. In particular, we recover Knott's equations this setting. show that knowle...

We construct microlocal solutions of Rayleigh and Stoneley waves in isotropic linear elasticity with the density Lamé parameters smooth up to a curved boundary or interface. compute direction polarization show retrograde elliptical motion these two type waves.
