Abstract :
The theory of tunable TE01¿ mode dielectric resonators containing circumferentially magnetized ferrites is developed. A solution of the electrodynamic problem is based on the Rayleigh-Ritz method. It is shown that such resonators can effectively operate as tunable devices with tuning range up to 2%.
