TL;DR: In this paper, the aspect ratio of the gyromagnetic resonator and susceptance slope parameter of the junction are discussed in the case of the evanescent E-plane junction loaded by H-plane open HE/sub 11.5/ gyromagnetic resonators.
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 HE/sub 11.5/ gyromagnetic resonators. The primary physical variables are the radial wavenumber of each resonator and the spacing between them. The schematic diagram of an E-plane circulator is depicted. >

TL;DR: In this article, the design, simulation and enhancing performance of a new structure for X-band high power, low loss, low bias, triangular-ferrite waveguide circulator is presented.
Abstract: The design, simulation and enhancing performance of a new structure for X-band high-power, low-loss, low-bias, triangular-ferrite waveguide circulator is presented. Dual circulation property is obtained by triangular shape of ferrite post. The effects of circulator's structure parameters, such as ferrite parameters and magnetic DC bias, on isolation, insertion loss and return loss of circulator are discussed. 20dB return loss, 20dB isolation and 0.1 dB insertion loss in dual frequency in X-band (8.2 Ghz & 10.4 Ghz) with only a magnetic bias of 10 Oe are obtained from CST Microwave Studio and Ansoft HFSS simulations which have good agreement to each other and shows remarkable response of those type of circulators.

The HFSS software is used for simulating the circulators. Final dual band designs with 20 dB return loss, 20 dB isolation and 0.1 dB insertion loss in dual frequency in X-band (8.2 GHz and 10.4GHz) with only a magnetic bias of 10Oe are obtained.
