1. On multilayered system dynamics and waves in anisotropic poroelastic media
Sammanfattning : The mechanical and acoustic anisotropy of media is a governing factor in the behaviour of multilayered systems including such media. The understanding of the mechanisms conditioning the dynamic behaviour of multilayered systems is of paramount importance. LÄS MER
2. Elastic Wave Propagation in Anisotropic Media. Application to Ultrasonic NDT
Sammanfattning : The subject of this thesis is elastic wave propagation in anisotropic materials with application to ultrasonic nondestructive testing (NDT). The first part of the thesis is concerned with modeling of ultrasonic transducers and wave propagation in anisotropic materials in general. First, a scalar 2-D case is considered. LÄS MER
3. Elastic wave scattering from corrugated surfaces in anisotropic media
Sammanfattning : .... LÄS MER
4. Manipulation of Light with Transformation Optics
Sammanfattning : Transformation optics, a recently booming area, provides people a new approach to design optical devices for manipulating light. With transformation optics, a lot of novel optical devices are proposed, such as invisibility cloaks, optical wormholes, optical black holes, illusion devices. LÄS MER
5. Multiphase continuum modeling of wood : A hybrid mixture theory approach
Sammanfattning : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. LÄS MER
