Evaluation of Absorptive Properties and Permeability of Thin Sheet Magneto-Dielectric Materials
Abstract
An analytical model to evaluate attenuation on the coaxial line with the central conductor coated with a magneto-dielectric layer is proposed and validated by the experiments and numerical modeling. This model is convenient for comparing absorptive effectiveness of different materials, as well as of different thicknesses and lengths of the same material. The proposed model also lays the basis for the technique to extract permeability of thin sheet magneto-dielectric materials by wrapping them around a central conductor of the coaxial airline.
