Permeability analysis of magnetic alloy thin films in inductance transmission line

► Permeability of Co-Fe film in inductance transmission line was analyzed up to 13.5 GHz. ► The results were in good agreement with the coupled Landau-Lifschitz and eddy current theories. ► Applicable requirements μ′rs⪡∼2500 and μ′rsfk⪡∼6500 GHz were derived.
