吸波材料是指能将入射的电磁波转化成其他形式的能量(如机械能,电能和热能)而消耗掉的材料。本文较全面地介绍了吸波材料的应用前景。要获得性能优良的吸波材料,必须综合考虑电磁阻抗和阻抗匹配2种因素,尤其是材料的介电常数(ε),磁导率(μ)。单独的导电高聚物材料吸收频宽较窄,为满足未来的隐身材料质量轻,适应性强的特点,可以将导电高聚物与无机磁性材料复合出兼具有磁性和导电性的复合聚苯胺材料。
Absorber material refers to the incident electromagnetic waves can be converted into other forms of energy (such as mechanical energy, electrical energy and thermal energy) and consumed material. This article introduces the application prospects of absorbing materials more comprehensively. To get good performance of absorbing materials, we must consider the electromagnetic impedance and impedance matching two kinds of factors, especially the dielectric constant (ε), permeability (μ). In order to meet the requirements of future stealth material with light weight and strong adaptability, conductive polymers with inorganic magnetic materials can be composited with composite magnetic and conductive composite poly Aniline materials.
