圆台谐振腔和微波产生及传输装置可以形成一套和外界独立的微波谐振器系统.由于壁面上电磁压强差的作用,圆台谐振腔可能产生净电磁力,这需要从实验上给予证明.为此首先应对独立的微波谐振器系统进行调谐实验研究,使系统时刻处于谐振状态,这是实验证明净电磁力存在的重要保证.为此,本文对圆台谐振腔进行低信号调谐实验,同时配合调谐元件,准确地调试2.45 GHz频率下的谐振状态,分析温度对谐振状态的影响.实验结果表明该微波谐振器谐振频率2.44895 GHz、品质因数117495.0823,而且当腔体壁温升高时谐振频率减小、品质因数出现周期性振荡.
The circular cavity resonator and the microwave generation and transmission device can form a set of independent microwave resonator system with the outside world, which may need to be proved experimentally due to the difference of the electromagnetic pressure on the wall First of all, an independent microwave resonator system should be tuned experimentally to make the system momentarily resonate, which is an important guarantee for the existence of net electromagnetic force.Therefore, this paper presents a low-signal tuning experiment for the circular cavity resonator, , The resonant state at 2.45 GHz was accurately debugged and the influence of temperature on the resonant state was analyzed.The experimental results show that the resonant frequency of the microwave resonator is 2.44895 GHz and the quality factor is 117495.0823.When the wall temperature increases, the resonant frequency decreases, The quality factor shows periodic oscillations.
