Calculation and experimental measurement of the spectra of natural vibrations of ferrite resonators of nonreciprocal waveguide devices microwave and EHF

Abstract

In the proposed work, in the approximation of magnetic walls, an equation is obtained for determining the natural frequencies of the resonator, which can be used in the design of both E- and H-planar devices. The main laws of the spectra of natural vibrations of ferrite resonators and their influence on the electrodynamic parameters of nonreciprocal devices are revealed. Experimental results for E- and H-plane circulators are presented and discussed. The optimal procedure for configuring nonreciprocal ferrite devices is described.
