Mode charts of gyromagnetic planar ring resonators
TLDR
The modes and frequencies of demagnetised and magnetized planar disc, triangular, wye and hexagonal resonators have already been described in the literature as mentioned in this paper, and another resonator which has the required symmetry is the ring resonator.Abstract:
The modes and frequencies of demagnetised and magnetised planar disc, triangular, wye and hexagonal resonators have already been described in the literature. Another resonator which has the required symmetry is the ring resonator. Here we give the resonant frequencies of this type of gyromagnetic resonator.read more

Nonreciprocal devices using ferrite ring resonators
V.A. Dmitriyev,L.E. Davis +1 more
TL;DR: In this article, a ring structure requires a smaller diameter and ferrite thickness than a disc structure for the same frequency, and increased component density may therefore be possible at the expense of bandwidth.
