【摘要】 本文应用一般型谐振腔的变分方程,推导了平面型谐振腔谐振频率的特征方程。该方程具有稳定性质,且仅以金属带上的电流为未知参量,因而运算效率高。作为示例,文中数值计算了孤立的、边缘耦合的以及宽边耦合的悬置微带线矩形谐振腔,数值结果与相应文献的计算数据一致。更多还原

【Abstract】 The variational equation for general resonant cavities is used to derive the characteristic formula for the resonant frequency of the arbitrarily planar reso aators. The formula implicates the unknown currents only in the metallic strips and can be solved with little.As examples, the rectangular resonators with single, edgecoupled and broadside-coupled suspended striplines are computed and the numerical results are in good agreement with available data in literatures.更多还原
