探针耦合谐振腔的谐振频率分析

The variational solution of resonate frequency of the probe-coupled retangular cavity

用变分法结合简正波法建立起同轴线探针耦合谐振腔的输入阻抗的变分公式，并利用谐振时输入阻抗为零的条件建立起谐振频率的泛函，从而研究这种结构的谐振频率的变化情况．

The formulation of input impedance of the probe-coupled rectangular cavity is given by the variational method, and the fUnctional of the resonate frequency is obtained when the formulstion of impedance equals zero.Finally,the relation between the variation of resonate frequency and the structure is given.
