研究成果
The study presents a new model for analyzing multipactor effect in dielectric-loaded rectangular waveguides, demonstrating the factors driving this effect. Simulations show that under studied conditions, the spread of electron impact positions is relatively small, validating the effective electron model for high kinetic energies.
研究不足
The study is limited to partially dielectric-loaded rectangular waveguides under specific conditions. The model's accuracy depends on the assumptions and simplifications made, such as infinite waveguide length and monomode regime.
1：Experimental Design and Method Selection:
The study employs a theoretical model for simulations, including electron dynamics governed by the Lorentz force, electromagnetic field interactions, and secondary electron yield modeling. A velocity-Verlet algorithm is used for numerical solutions.
2：Sample Selection and Data Sources:
