1. Feedback control of resistive wall modes in the reversed field pinch
Sammanfattning : A wide range of unstable current driven MHD modes is present in the re- versed τeld pinch (RFP) conτguration. An ideally conducting wall facing the plasma can stabilize the ideal MHD modes. LÄS MER
2. Resistive Wall Mode Stability and Control in the Reversed Field Pinch
Sammanfattning : Control of MHD instabilities using a conducting wall together with external magnetic fields is an important route to improved performance and reliability in fusion devices. Active control of MHD modes is of interest for both the Advanced Tokamak and the Reversed Field Pinch (RFP) configurations. LÄS MER
3. Development of a method for highly localized growth of carbon nanotubes
Sammanfattning : A method for growing carbon nanotubes on chip using highly localizedresistive heating is developed. By deliberately designing molybdenumelectrodes to be highly resistive in a very small region we create amicrometer sized hot-zone where carbon nanotubes can be grown. LÄS MER
4. Simulations of Silicon Carbide Chemical Vapor Deposition
Sammanfattning : Most of the modern electronics technology is based on the semiconducting material silicon. The increasing demands for smaller electronic devices with improved performance at lower costs drive the conventional silicon technology to its limits. LÄS MER
5. Electromagnetic Simulation, Analysis and Design with Application to Antennas and Radar Absorbers
Sammanfattning : The present thesis considers two different subjects in the research area of electromagnetics. The first part is concerned with antenna design and the second with radar absorbers and rasorber.In the first part, a novel excitation technique for cylindrical dielectric resonator antennas is introduced to produce circular polarization.
