摘要
非对称谐振系统的磁控管中,模式分隔度得到提高,π模电场沿角向分布不均匀,呈现出明显的强电场区和弱电场区。分析表明,合理的利用这种分布,将输出结构放置在强场区,能够有效提高磁控管效率。通过仿真验证,与对称谐振系统磁控管比较,输出功率虽然从3.64 MW下降到3.21MW,但效率从35.17%提高到43.23%。
The application of asymmetric resonant system of the magnetron can improve mode separation.And the electric field distribution in π mode is not uniform along the angular orientation,so that form two regions—a strong electric field area and weak electric field area.The analysis shows that proper use of this distribution,placing the output structure in strong region,can effectively improve the efficiency of magnetron.Compared with symmetric resonant system of magnetron,it is proved by simulation that the output power drop from 3.64 MW to 3.21 MW,but the efficiency is increased from 35.17% to 43.23%.
