1. Multipactor in low pressure gas and in nonuniform rf field structures
Sammanfattning : Resonant electron multiplication in vacuum, multipactor, is analysed for several geometries where the RF electric field is nonuniform. In particular, it is shown that the multipactor behaviour in a coaxial line is both qualitatively and quantitatively different from that observed with the conventionally used simple parallel-plate model.

2. Microwave Breakdown: Physics and Applications
Sammanfattning : Theories for microwave breakdown in gases, with emphasis on Air, are presented in this thesis. Underlying physical processes are described together with models suitable for scientific research and technical development. LÄS MER
3. Modelling and simulations of multipactor discharges in microwave communication lines
Sammanfattning : .... LÄS MER
4. Optical Diagnostics of Non-thermal Plasmas and Plasma-assisted Combustion
Sammanfattning : Non-thermal plasma is regarded as a collection of free electrons, ions and neutral particles that are not at local thermodynamic equilibrium. The high-energetic electrons formed in non-thermal plasmas are capable of generating chemically active species and modifying chemical kinetics in practical applications. LÄS MER
5. Modelling and Applications of the Hollow Cathode Plasma
Sammanfattning : This thesis presents experimental and modelling research on atmospheric pressure hollow cathodes and hollow electrodes. Experiments with the hybrid hollow electrode activated discharge (H-HEAD), which is a combination of a hollow cathode and a microwave plasma source, is presented. LÄS MER
