A method for accurate measurement of liquid crystal (LC) dielectric constant at lower terahertz region based on a metamaterial absorber, is proposed. In the proposed method, the permittivities are obtained by fitting the simulated spectral responses to the measurement results of a metamaterial (MM) absorber, in which LC layer acts as a substrate. The proposed method was verified by measurement of dielectric anisotropy of two LC mixtures, and error analysis has shown that the maximum error of the extracted permittivity was less than 1%.
