Abstract

In this work, we report on the observation of the electromagnetic parameters of glass-covered amorphous microwires/epoxy composites with various concentrations of microwires over a broad magnetic field range up to 1 kOe. The effective permittivity presents a strong tunability with respect to a dc magnetic field excitation. An inherent crossover field due to the microwires is further observed at 300 Oe suggesting that the giant magnetoimpedance effect dominates the features of dipolar absorption at low magnetic field bias (
