Аннотация:The permeability of layered composites (laminates) is measured at frequencies 0.1-10 GHz. The laminates consist of alternating iron and Mylar films. The continuous or patterned iron films 0.1-1 mum thick are produced by magnetron sputtering. The intrinsic permeability spectra of metal inclusion are parametrically reconstructed. The obtained parameters of magnetic resonance are compared to the theoretical constrains derived for a perfect infinite film. The effect of film thickness upon the permeability of the laminate is discussed. The microwave permeability of the laminates under study is comparable with that of composites filled with carbonyl iron.
