Abstract

The aspect ratio of the gyromagnetic resonator and susceptance slope parameter of the junction are important parameters in the design of a junction circulator. The purpose of this paper is to provide some additional information on these two quantities in the case of the evanescent E-plane junction loaded by H-plane open HE11 1/2 gyromagnetic resonators. The primary physical variables are the radial wavenumber of each resonator and the spacing between them. The design of a quarter-wave coupled device is outlined separately.
