Abstract

Axially magnetized ferrite phase‐shift sections can be biased above or below ferrimagnetic resonance. Mode charts displayed in terms of frequency/bias field, rather than tensor entries, cater for partial magnetization. From this construction it is shown that TM modes have separate onset frequencies above and below ferrimagnetic resonance leading to unique modal hierarchies in each region. For one waveguide structure the theoretical cutoff numbers are compared with experimental data and the phase‐shift calculations are separately corroborated by finite‐element solutions. © 1995 John Wiley & Sons, Inc.
