An Improved Method of Determining Permittivity and Permeability by S Parameters
In the paper, a new method is presented for determining the complex permittivity and permeability of the linear materials by scattering coefficients. The coaxial line fixture is used to facilitate the measurement of the materials S Parameters. With the S Parameters, the complex permittivity and permeability of the linear materials as a function of frequency can be determined by the method. The phase ambiguity of the imaginary part of propagator can be resolved by the real part of S21.Compared with former methods, the period of propagator can be got from a series of reflection and transmission S Parameters in the frequency domain, the results of the improved method can be more accurate in the wideband.
