Abstract

The effect of the external magnetic field on the dispersion of the effective permittivity in arrays of parallel CoFe-based amorphous wires is demonstrated by measuring S-parameters in free space in the frequency band of 0.9-17 GHz. The magnetic field is applied along the wires sensitively changing their magnetization and high frequency impedance. Based on the measurements of magneto-impedance in a single wire and transmission/reflection spectra of composites in free space, we show the correlation between magneto-impedance and the field dependence of the effective permittivity.
