6. Using multiple SIMD architectures for multi-channel radar signal processing
Sammanfattning : .... LÄS MER
7. Fully metallic antennas for millimeter wave applications
Sammanfattning : Modern societal demands for a high data throughput, short time latency and low energy consumption are difficult to satisfy using current wirelesscommunication techniques. The carrier frequency of previous wireless communication, such as broadcast, the global system for mobile communication, and wireless local area networks, are in the sub-3 GHz spectrum. LÄS MER
8. Nanoscale technologies for plasmon-assisted solar light harvesting and lipid membrane composites
Sammanfattning : Techniques for design, manipulation and characterization of nanoscale structures provide the basis for technological advances in areas like optics, electronics and biotechnology. The aim of this thesis is to develop new nanoscale methods and design schemes that extend the applicability of nanoscale devices. LÄS MER
9. Tinkering with Light at the Nanoscale using Plasmonic Metasurfaces and Antennas: From Fano to Function
Sammanfattning : Surface plasmons are charge density oscillations that can couple strongly to light and be excited in, for instance, thin metal films and metal nanoparticles. The plasmonic excitation squeezes the light down to nanometric length scales, far smaller than the wavelength of the light. LÄS MER
10. Molecular Trees for Collecting Sunshine -Monitoring and Controlling Energy Transfer in Dendrimers
Sammanfattning : A continuing use of fossil fuels will accelerate global warning and result in severe consequences for the environment and thereby also us. Development of alternative, sustainable and environmentally friendly energy sources is therefore crucial. One approach is to create an artificial photosynthetic system that converts sunshine into fuel (e.g. LÄS MER
