Bai J. Localization and dispersion of normal elastic waves in composite anisotropic waveguides

Dissertation is devoted to the theoretical investigation of dispersion spectra and properties of generalized surface and normal waves in elastic anisotropic waveguides, which consist of two dissimilar monocrystal orthorhombic half-spaces, layer and half-space or two layers. Dispersion relations for the wave in arbitrary propagation direction in the plane of perfect or slider contact of waveguides component have been constructed and investigated. Properties of generalized Stoneley and Love surface waves in three-dimensional waveguides are studied. The cinematic and energetic characteristics of normal and generalized surface waves are investigated. Structure and features of full spectra of normal wave in monocrystal two-layer plate are studied. The qualitative and numerical investigation of regularities of the localization in high-frequency short-wave band for running normal elastic in bilayer waveguides is carried out.
