Abstract

The uncertainty of measurements of the complex permittivity ε_r and permeability μ_r as a function of the normalized sample length l/Λ´ due to the measured errors in the scattering coefficients S₁₁ and S ₂₁ is discussed. A simple analysis of ε_r and μ_r and some measured data are given, which allows one to determine the extent of l/Λ´ and maximum uncertainty of the combined total transmission-reflection method in application to radar absorber measurements
