摘要

本文介绍了含不同直径玻璃包覆磁微线的复合辐射材料的电磁响应研究结果。研究了复合金属反射率在10 MHz ~ 18 GHz范围内的频率依赖性。结果表明，所得样品具有体共振，在较窄的频率范围内吸收增加。随着样品厚度的减小，共振转移到更高的频率。通过改变复合材料中的微丝浓度，可以将共振时的反射系数降低到-48 dB，或者在高填料浓度的情况下，如果克服了渗透阈值，则可以获得完全反射的材料。

Microwave electromagnetic properties of composite radiomaterials based on magnetic microwires

This paper represents the results of the research of electromagnetic response of composite radiomaterials containing glass-coated magnetic microwires of different diameters. The frequency dependence of the composite metal reflectance in the range from 10 MHz to 18 GHz is studied. The paper shows that the obtained samples have bulk resonance and there is an absorption increase within a narrow frequency range. With reducing the thickness of the sample the resonance shifts to higher frequencies. By varying microwire concentration in the composite it is possible to reduce the reflection coefficient at resonance to -48 dB or to get completely reflective material if overcoming the percolation threshold in cases of high filler concentration.
