The complex electrical permittivity and magnetic permeability of composite materials made of a polymer binder filled with micron-scale carbonyl iron powder (CIP) are measured between 0.1 and 39 GHz. Permeability is measured in overlapping frequency subbands using two different techniques: a free-space method from 3 to 39 GHz and a coaxial impedance cell from 0.1 to 5 GHz. The dependence on filler concentration is studied for composites based on phosphated CIP R-100F-2. It is found that the static permittivity and permeability of the composites increase logarithmically with increasing percentage of CIP volume loading; this corresponds to Lichtenecker’s law for a mixture of two components. It is demonstrated that by using the R-100F-2 type CIP it is possible to produce single-layer radar-absorbing materials with a relatively small thickness (less than 1.5 mm) and a deep and broad normal-incidence reflectivity minimum (less than −20 dB) from 10 to 30 GHz.

超宽频段羰基铁粉复合材料的复介电常数和磁导率
在 0.1 和 39 GHz 之间测量由填充有微米级羰基铁粉 (CIP) 的聚合物粘合剂制成的复合材料的复介电常数和磁导率。使用两种不同的技术在重叠频率子带中测量磁导率：3 至 39 GHz 的自由空间方法和 0.1 至 5 GHz 的同轴阻抗单元。研究了基于磷化 CIP R-100F-2 的复合材料对填料浓度的依赖性。发现复合材料的静态介电常数和渗透率随着 CIP 体积负载百分比的增加呈对数增加；这对应于两种成分的混合物的 Lichtenecker 定律。
