基于传输线理论的电磁波反射系数正交分析研究

分析电磁参数对电磁波反射系数R的影响是电磁波屏蔽吸波研究的热点之一。考虑到影响电磁波反射系数R的因素很多,同时研究多个因素而成为关键点。在前人学者基础上,基于传输线理论,利用正交试验设计进行安排试验,分析研究电磁参数的四个因素以及电磁波频率f、吸波层厚度d六个因素对反射系数的影响。模拟实验结果表面： 对电磁波的反射系数R的影响大小分别为吸波层厚度d、相对复磁导率虚部 、相对复磁导率实部 、相对复介电常数虚部 、电磁波频率f、相对复介电常数实部 ；在X波段区间内,吸波层厚度d对电磁波反射系数具有显著影响,而相对复介电常数实部和虚部、相对复磁导率实部和虚部、电磁波频率产生影响,但不够显著。

The influence of electromagnetic parameters on the reflection coefficient R of electromagnetic wave is one of the hotspots in electromagnetic wave shielding. Considering the factors that affect the reflection coefficient R of the electromagnetic wave, it is a key point to study several factors, On the basis of previous scholars, based on the transmission line theory, using orthogonal test design to arrange the test, the four factors of the electromagnetic parameters and the influence of the frequency of the electromagnetic wave f and the thickness of the absorbing layer d on the reflection coefficient were analyzed. Simulation of experimental results Surface: The influence of the reflection coefficient R of the electromagnetic wave is the thickness of the absorbing layer d, the imaginary part of the relative complex permeability , the real part of the complex permeability , the imaginary part of the complex permittivity , the frequency of the electromagnetic wave f , Relative complex permittivity real part ;in the X-band interval, the thickness of the wave-absorbing layer d has a significant effect on the reflection coefficient of the electromagnetic wave, And the relative complex permittivity real and imaginary parts, the relative complex permeability of the real and imaginary parts, the electromagnetic wave frequency has an impact, but not significant.
