Symmetry-induced modal characteristics in uniform waveguides or resonators with ferrite rods

A technique of symmetry analysis for modal characteristics in uniform waveguides or resonators with ferrite rods is presented here. Symmetry analysis can provide basic information concerning modal characteristics. After summarizing the basic principles of symmetry analysis, some points concerning symmetry operations are discussed. Then the process of symmetry analysis is applied to structures, i.e. uniform wave guides withC _n symmetry or symmetry and resonators withD _nh symmetry in which exist longitudinally magnetized ferrite rods. Finally, results of the symmetry analysis are given in four tables.
