摘 要: 采用最小二乘法拟合得到了复介电常数的频谱特性方程,理论计算了炭黑材料涂覆于金属板上、在不同涂层厚度时的微波吸收特性,并用最小二乘法优化得到了最佳涂层厚度。电介质型炭黑材料的复介电常数的频谱数据在1~10 GHz间,遵从德拜弛豫模型,并与最小二乘法拟合的结果一致。表明最小二乘法是研究和分析材料微波吸收特性的一种有效方法。
关 键 词: 微波吸收材料;炭黑;最小二乘法;最优厚度;德拜极化弛豫方程

Abstract: The relationship between the complex permittivity and frequency was represented by least square method, the microwave absorption properties of the carbon blacks coated on the metal were calculated theoretically, furthermore, the optimal coat thickness relating to the optimal microwave absorption was gained through least square method. The complex permittivity between 1 and 10 GHz can be described by Debye equations, which is corresponding with the data gained from least square method, it shows that the least square method is the effect way to investigate the microwave absorption properties of the absorbers.
Key words: microwave absorption material; carbon black; least square method; optimal thickness; Debye polarization-relaxation equation
