A New Method of Measurements of All Complex Permeability Tensor Components of Microwave Ferrites using One Cylindrical Ferrite Sample

A new msthod of measurements of all complex permeability tensor components of microwave ferrites, using one cylindrical ferrite sample is presented. Two dielectric ring resonators having the same heights and internal diameters but different external diameters operating on HE± 111 and H011 modes respectively are applied for measurements. Permeability tensor components are computed from the measured resonant frequencies and Q-factors of these resonators with and within ferrite sample. Computations are based on the exact eigenvalue equations for this modes.
