摘要

目的为实现对电磁复合材料在平面电磁波斜入射下的电磁特性进行分析与优化,提出一种测量斜入射下电磁复合材料等效电磁参数的方法。方法引入入射角参数构建斜入射下等效电磁参数反演算法,并利用金属板和空气的传输-反射校准技术实现斜入射下散射参数的精确测量。结果搭建了一套8~12 GH测试系统,对蜂窝等材料的等效电磁参数进行了测试;基于测试值对其反射率进行了计算并与弓形法测试结果进行比对,两者偏差在0.5 dB以内,表明该方法具有良好的准确性。结论本研究为电磁复合材料的电磁性能评价提供了一种有效测试方案,简化了复杂结构的仿真建模与设计。

Abstract

The work aims to propose a method for measuring the equivalent electromagnetic parameters of electromagnetic composites under oblique incidence, so as to analyze and optimize the electromagnetic characteristics of electromagnetic composites under oblique incidence of plane electromagnetic waves. An incident angle parameter was introduced to develop an inversion algorithm for obtaining equivalent electromagnetic parameters at oblique incidence. Scattering parameters at oblique incidence were tested accurately using the transmission-reflection calibration technique, where a metal plate and air were used. An 8-12 GHz test system was constructed to measure equivalent electromagnetic parameters of typical materials, such as a honeycomb. The reflectivity was calculated based on the test data and compared with arch-method test results; The deviation between the two was less than 0.5 dB, indicating high accuracy of this method. This work provides an efficient testing solution for evaluating electromagnetic properties of electromagnetic composites; it also greatly simplifies the simulation modeling and design of complex structures.
