Abstract
In this article a new approach for accurate prediction of scattering parameters of lossy dielectric materials is suggested. It is based on reconstructing complex permittivity profile of the test cell placed within rectangular waveguide and numerical determination of proper scattering parameters using algorithm Kao or its modification. Both propagating and evanescent modes excited in the test cell consisting of the dielectric tube filled with lossy materials are investigated to validate resonance and non-resonance phenomena. Comparison with earlier reported results shows a good agreement. The advantage of this method is the simplicity of its realization and accuracy in prediction of scattering parameters measured in practice.
