【摘要】 随着无线通讯技术的发展,其占用的频谱与微波炉磁控管的频谱接近,为了抑制磁控管的频谱噪声,本文采用三维粒子模拟软件MAGIC,对某微波炉磁控管进行精确地建模,分别在均匀磁场和实际分布不均匀的三维磁场情况下进行模拟,根据计算的起振电流、输出电压和输出频谱说明,当磁控管内的磁场分布适当不均匀时,有利于磁控管快速起振,改善输出频谱。但磁场的非均匀效应有待进一步研究,并通过实验进行验证。更多还原

【Abstract】 With the wireless communication development, the its working spectrum is very close to the output spectrum of microwave oven magnetron. To reduce spectrum noise of magnetron, the precise model of the magnetron is created by the three dimensional PIC code-Magic. Compared the uniform magnetic fields with the practical non-uniform three dimensional magnetic fields, the simulation is done to obtain the start oscillation current, output voltage and.output spectrum. When the magnetic fields have appropriate non-uniform distribution in the magnetron, the fast stat oscillation and better output spectrum is obtained in the simulation result. But the non-uniform influence of the magnetic fields will spend the more research and the validation by the experiment.更多还原
