Abstract
The propagation of electromagnetic waves in a ferrite image line was theoretically formulated. The formulation was based upon the effective permeability approach. The ferrite image line consisted of an insulating slab of ferrite with a rectangular cross section overlaid on an electrical ground plane. The ferrite was purposely magnetically biased so that FMR coincided with the band of frequencies in which propagation is allowable in the waveguide structure. Insertion loss and phase shifts of the electromagnetic wave signal was calculated as a function of frequency. We suggest that ferrite phase shifters, isolators, filters, and switches operating at the millimeters wavelength may be feasible using this guided structure.
