An effective simultaneous evaluation method for the complex permittivity and permeability of lossy materials is proposed by applying it to an arbitrarily shaped cross-sectional post placed in a rectangular waveguide. We use one sample and only measure S21 parameters for two different locations of the sample. The measurement of complex reflection parameter S11 is not required in this evaluation method...
The extended spectral domain approach combined with the mode-matching method (ESDMM) is applied to analyze the scattering characteristics of lossy dielectric post with arbitrarily-shaped cross section in the rectangular waveguide. ESDMM is accurate and efficient, and it is suitable for the iterative fitting to estimate the material characteristics. An effective evaluation method is proposed for the...
