1. Twist-Symmetric Periodic Structures : Properties and Applications
Sammanfattning : In this thesis, periodic structures with higher symmetries symmetries are discussed. The main focus of the thesis is on twist symmetries. Importantly, the attractive properties of twist symmetries for the control of electromagnetic wave propagation are demonstrated. LÄS MER
2. Planing wood with twist
Sammanfattning : About half the total volume of sawlogs end up as sawn timber. The rest is lostdue to drying shrinkage or is turned into byproducts like wood chips, sawdustand shavings. As the raw material is a large expense for a sawmill, it is important to fully utilize the logs. LÄS MER
3. Plasmonics with a Twist
Sammanfattning : This thesis focuses on the exploration of interactions between circularly polarized light and plasmonic nanostructures, and nanoparticles. Polarization is an integral part of light and has a wealth of applications in the modern world. LÄS MER
4. An Antiferroelectric Twist Grain Boundary Phase
Sammanfattning : .... LÄS MER
5. Moisture-induced distortion in timber structures - examples based on partition walls
Sammanfattning : The shape of timber changes due to variations in moisture content (MC). In Scandinavia, producers normally dry timber to an MC of 18%. However, after the studs are built into the wall structure, for example, they may become distorted as a result of further drying in the structure. The final MC in a heated building in Scandinavia is about 8%. LÄS MER
