In this article, an equivalent circuit approach has been used to study the bifrequency generation by the azimuthally partitioned axially periodic metal disk-loaded coaxial structure. Considering the effect of all harmonics present within the structure and using an equivalent circuit approach, the expression of the equivalent series inductance per unit length and equivalent shunt capacitance per unit length has been obtained for this equivalent transmission line. In addition, with the help of computed equivalent series induction and equivalent shunt capacitance, expressions for the dispersion relation, phase velocity, and characteristic impedance have been obtained. The maximum possible frequency difference (i.e., bandwidth) between the modes (i.e., resonating frequency) and its region of operation have also been analytically computed. Finally, the parametric studies have been performed to find out the effect of structural parameter variation on dispersion behavior. In order to validate the numerical analysis, the structure has been first simulated with the help of CST microwave studio, and then, the analytically obtained results (such as dispersion behavior and phase velocity) have been compared with the results obtained from simulation. The comparison of results shows that the relative error is below than 5%, which shows a good agreement between them.

等效电路法分析双频MILO方位角分割周期盘加载同轴结构

在本文中，等效电路方法已被用于研究由方位角分隔的轴向周期性金属圆盘加载同轴结构产生的双频。考虑到结构中存在的所有谐波的影响并使用等效电路方法，已经获得了该等效传输线的单位长度等效串联电感和单位长度等效并联电容的表达式。此外，借助计算的等效串联电感和等效并联电容，得到了色散关系、相速度和特征阻抗的表达式。模式（即谐振频率）与其工作区域之间的最大可能频率差（即带宽）也已被分析计算。最后，已进行参数研究以找出结构参数变化对色散行为的影响。为了验证数值分析，首先在CST微波工作室的帮助下对该结构进行了模拟，然后将解析得到的结果（如色散行为和相速度）与模拟得到的结果进行了比较。结果对比表明，相对误差小于5%，表明它们之间具有良好的一致性。分析获得的结果（如色散行为和相速度）与模拟获得的结果进行了比较。结果对比表明，相对误差小于5%，表明它们之间具有良好的一致性。分析获得的结果（如色散行为和相速度）与模拟获得的结果进行了比较。结果对比表明，相对误差小于5%，表明它们之间具有良好的一致性。
