An Effective Method for Electromagnetic Parameter Measurement of Flexible Materials Based on Air Coaxial Line

Figure 6

Comparison between measurement results and reference values (the measurement results in blue are based on the proposed method in this paper and the reference values in red are based on the method in standard ASTM D7449): (a) real part of relative permittivity, (b) imaginary part of relative permittivity, (c) real part of relative permeability, and (d) imaginary part of permeability.
