Complex permittivity of dielectric materials loaded in the cross section of a rect-angular 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.
