Hybrid technique for the analysis of circular waveguide junctions loaded with ferrite posts

This study presents a hybrid technique for the analysis of circular waveguide junctions loaded with axially symmetrical ferrite posts of irregular shape. The method is based on a combination of the finite-difference frequency-domain technique with a mode-matching technique. The proposed approach is validated by comparing the presented results with numerical ones obtained from commercial software. The application of a cylindrical junction loaded with ferrite posts with reciprocal and non-reciprocal devices is presented and discussed.
