Passive ferrite resonator-based millimeter wave band components

The review of magnetodynamic resonances in ferrite resonators and their mm-wave band applications was given. Ferrite resonator eigenexcitations classification has been presented. The analytical theory for modes resonant frequencies calculations is stated and a number of prototype electronically tunable mm-wave devices, utilizing the “above” and “below FMR” magnetodynamic resonances, including isolator, phase shifter, band-pass and band-stop filters have been demonstrated.
