摘要：

A radar microwave absorbing material was designed by integrating Co-based amorphous microwires and Ce2Fe17N3-delta composites. The complex permittivity and permeability of the Co-based amorphous microwires gridding was measured by Vector Network Analyzer (VNA), which display magnetic resonance and dielectric resonance near 10 GHz. The microwave absorption behavior of the Co-based amorphous microwires gridding tested by VNA shows that absorbing bandwidth below -10 dB was broadened to 3.6 GHz in X-band as integrated with Ce2Fe17N3-delta composites. The mechanism of efficient microwave absorption in X-band were also discussed, which incorporated the microwave absorption characters of electromagnetic resonance and l/4 wavelength matching absorption.
