Relation between Power Dissipation and Signal Transmission Characteristic in CoZrNb/Polyimide Hybrid Microstrip Line

概要

論文の詳細を見る
RF hybrid microstrip line with a Polyimide(1 μm)/CoZrNb(1 μm)/Polyimide(1 μm) sandwich was fabricated and characterized. The hybrid microstrip line exhibited a large effect of the wavelength-shortening, and the large signal-decay at around or over the intrinsic ferromagnetic resonance (FMR) frequency. To discuss the effect of the power dissipation on the signal transmission was discussed on the basis of the experimental results and power loss estimation using the electromagnetic field analysis with taking the FMR into account. The insertion loss around or over the intrinsic FMR point was not only owing to the FMR absorption, but also owing to the eddy current enhancement by skin effect anomaly by the FMR.
