摘要: 本文采用平板反射方法,利用与无反射曲线具有同源性的条件选择曲线,探索出了一种反演等效复介电常数的新方法。研究表明,通过选取无反射曲线上的点进行的理论模拟,并对不同厚度样品吸收曲线进行模拟反演和实验值对比,结果相当吻合。本研究可为测试各种大尺寸、多孔材料、液体等样品等效介电常数提供了一种行之有效的方法,对内部多相大结构电磁功能复合材料的设计研究具有重要意义。

Abstract: A new method of inversion equivalent complex permittivity is explored in this paper based on flat-reflection method and the conditions-selection curve which has homology with the non-reflective curves.The research shows that the results between theoretical simulation by choosing the points on non-reflective curve and experimental of the absorption curve of different thickness samples are all in good agreement.This study provides an effective method for testing the equivalent permittivity of a variety of large size,porous materials,liquid samples etc,which has an important significance for the design of electromagnetic functional composite material with large multiphase internal structure.
