摘要：The influence of electromagnetic parameters on the electromagnetic wave reflection coefficients(R) is one of the hot spots in electromagnetic shielding and wave absorbing.Many factors have influenced the electro-magnetic wave reflection coefficients,while studying a number of factors becomes a key point.On the basis of sev-eral scholars' previous researches,based on the transmission-line theory,the real part of the complex permeability (μ′),the imaginary part of the relatively complex permeability(μ″), the real part of the complex permittivity (ε′),and the imaginary part of the complex permittivity(ε″)are the four factors considered.Furthermore,the in-fluence of the electromagnetic wave frequency(f)and the thickness of the absorbing layer(d)on the reflection co-efficient is also analyzed by designing an orthogonal test.Experimental simulation results show that the parameter d has a significant effect on the R in the X-band interval, while the parameters μ″,μ′,ε″,ε′and f have insignificant impacts.
