Transmission-reflection methods suffer from the increasing uncertainty in the phase of reflection scattering ( S-) parameter measurements of low-loss materials. In addition, transmission S -parameter measurements produce multiple solutions for the complex permittivity. In this paper, we propose a broadband and stable method for unique complex permittivity determination of low-loss materials by eliminating these problems. For elimination of the phase uncertainty problem, we utilize only the… CONTINUE READING
