Abstract :
In this paper various nematic liquid crystal mixtures are investigated at 30 GHz. The used cavity perturbation characterization method enables the precise extraction of permittivity and dielectric losses. The three investigated matrices show a strong influence in the material quality factor eta, defined as the ratio between the tunability tau and the maximum dielectric losses tandeltamax, ranging between etaap3.2 ... 12.5.
