摘要: 该文指出准周期边界条件法在耦合腔高频特性研究的应用中会出现伪解，提出了相移法和能量法对伪解进行辨别，并初步探讨产生伪解的原因，然后提出了去除伪解的理论分析法和相移法，其中相移法具有普遍性。最后给出了该方法在休斯型耦合腔结构中的应用算例。Abstract: This paper points out that the fake solutions appear when the quasi-period boundary condition method is applied to the coupled-cavity structure. Phase method and energy method are presented to identify the fake solutions. Then, the cause of fake solutions is made out. Theory analysis and phase method is presented to eliminate the fake solutions. Finally, the application of the method on Huges coupled-cavity structure is carried out as an example.
