Abstract
The purpose of the presented work is an accurate determination of magnetic loss far from gyromagnetic resonance (ΔHeff), in a wide frequency range using resonant cavities completely or partially filled with magnetic material. The rigorous analytic field expressions are given for any mode of each device. The importance of the relative metallic loss is pointed out and the accuracy of the determination of the conductivity of metallic walls is discussed. The accuracy of the ΔHeff determination is studied for each structure
