Eztraction of Complez Permittivity of Multilayered Dielectric Sample Loaded in a Rectangular Waveguide

摘要：

Complex permittivity of dielectric materials loaded in the cross section of a rectangular waveguide can be determined from the S-parameter measurements of the discontinuity. The analytical electromagnetic tool used to solve the scattering problem of dielectric loaded waveguide is mode matching method. Minimization of an error function to extract the unknown complex permittivity of the material is done using a practical Quasi-Newton algorithm.
