Optimization of microwave power transfer from electric field to the plasma inside an microwave 915 MHz plasma source

This paper presents an optimization of the waveguide-supplied coaxial-line-based nozzleless microwave plasma source. This field applicator operated at a frequency f equal to 915 MHz at an atmospheric pressure. The optimization objective was to maximize an efficiency of power transfer from electric field to plasma inside this device. In the optimization we used a model of plasma which was determined in this work.
