Ferrite resonance isolators in coaxial, strip, and rectangular waveguides with a dielectric

Abstract

An analysis is given of ferrite resonance isolators in coaxial and strip lines and in a rectangular waveguide containing a dielectric. The analysis is based on numerical calculations (using a computer) using the results obtained in [1]. The results enable us to estimate the influence of the thickness of the dielectric, its permittivity, the ferromagnetic resonance line width and other parameters, upon the bandwidth of the system and upon the optimum magnetization ensuring the maximum isolation for the chosen system parameters and center frequency of the band. In this paper the terminology used is the same as in [1].
