摘要: In the above paper authors concluded, from a modal analysis of microstrip ferrite circulators, that combination two adjacent modes should be used for broad-banding which do not require quarter-wavelength matching transformers. Upon careful examination their results, it can shown Miura and EIashimoto actually produced conventional below resonance circulators---transformers included.
