Abstract :
This paper describes a simple method of measurements the complex permeability of yttrium iron garnet (YIG) substrates. The permeability of YIG is measured near a ferromagnetic resonance. The method is based on the measurements of resonant frequencies and Q-factors of YIG substrate placed into two structures: single post dielectric resonator and split post resonator. The obtained results are presented.
