研究目的
Investigating the microwave electromagnetic fields in magnetized plasma-filled reactors to understand the complex patterns observed and identify them as Trivelpiece–Gould waves.
研究成果
The study successfully identified the complex jagged patterns observed in ECR plasma reactors as Trivelpiece–Gould waves, validating the use of FEM for detailed electromagnetic field analysis in such systems. This approach enables the identification of very fine wave structures, offering insights into plasma behavior and potential improvements in reactor design.
研究不足
The study focuses on numerical simulations and theoretical analysis without experimental validation. The complexity of electromagnetic wave field analysis in magnetized plasma-filled reactors may introduce uncertainties.
