Abstract
Single circulation frequency operation (SCFO) Y-ring circulators have been explored in earlier papers, where their inner circumference has been assumed to exhibit a magnetic wall (MW). In this paper, a new design is given using air in the center of the ring and treating the ring circulator as a composite dielectric-ferrite (DF) circulator. This DF circulator offers a wider bandwidth than the MW ring component
