Enforcing Spectral Continuity of Complex Dielectric Permittivity Values For RFM

Abstract

We present an alternative version of the Rational Functional Method (RFM) which can explicitly retrieve the Debye parameters of the material under test (MUT) without any data fitting. A simulation of the open-ended coaxial probe with the MUT is performed to obtain the reflection coefficient from 0.5 to 6 GHz. A newton-based inversion method is used to reconstruct the Debye parameters of the MUT, and the complex dielectric property (CDP) variation on the measurement spectrum is calculated via these model parameters. The error rate for the reference materials formamide, methanol, and chlorobenzene is 2.7-8.6 %. The numerical results show that retrieving Debye parameters with the proposed inversion method is possible.
