一、引言目前只求出了一些几何形状(如立方体、球体、正圆柱体、椭球体及椭圆柱体等)很简单的微波谐振腔的谐振频率的解析解。用变分法和微扰法可计算出与上述基本形状有微小差别的腔体的谐振频率,但这些方法只用于局部有偏差的情况(如圆腔体表面有小的局部畸变的情况)。本文提出一种经大量微波谐振频率 I. INTRODUCTION At present, only the analytical solutions of the resonant frequencies of microwave resonators whose geometry is very simple (such as cube, sphere, regular cylinder, ellipsoid and elliptic cylinder) are obtained. Resonance and perturbation methods can be used to calculate the resonant frequencies of cavities that differ slightly from the basic shapes described above, but these methods are only used for localized deviations (for example, small localized distortions on the surface of a circular cavity) . This paper presents a large number of microwave resonant frequencies
