  2. 1. Direct and inverse resonance problems for seismic surface waves

    Author : Samuele Sottile; Matematik (naturvetenskapliga fakulteten); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inverse problems; Resonances; Spectral theory; Love waves; Rayleigh waves;

    Abstract : This thesis concerns the investigation of direct and inverse resonance results for the Love and the Rayleigh operators, which arise from decoupling the three-dimensional elastic wave equation in the semiclassical limit in the half-space. Direct resonance results in terms of the asymptotic distribution of resonances in the complex plane are obtained for the Love and the Rayleigh operators. READ MORE

  4. 2. Guided Elastic Waves along Periodically Corrugated Structures

    Author : Ahmed M. A. El-Bahrawy; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present thesis consider time-harmonic surface and guided elastic waves propagating along periodically corrugated structures. The problems discussed deal with various configurations where the surfaces are sinusoidally - singly or doubly - periodic, and the interest is focused on investigating the roots of the dispersion relations and in particular the stopband and cross-over resonances.

  5. 3. Nanomechanical Phenomena in Low-Dimensional Structures

    Author : Anton Vikström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; superconductivity; acoustic sensors; heat flow; NEMS; surface acoustic waves; solitons; viscoelasticity; electronic edge states;

    Abstract : This is a compilation thesis which investigates various mechanical phenomena in different low-dimensional nanoscale systems. In the first part, we consider a purely mechanical phenomenon: the sensitivity of the dispersion of a Love-type surface acoustic wave (SAW) to geometry and material parameters. READ MORE
