在300 ~ 1500 GHz频率范围内测量了双相液晶（LC）混合物的介电性能。测量是在一个标准的太赫兹TDS设置。平行和垂直取向的折射率和消光系数进行计算，并在19 GHz的结果进行比较。所研究的混合物对于太赫兹器件是有意义的，因为它们的特性在19 GHz至1500 GHz之间几乎保持不变。
The dielectric properties of nematic liquid crystal (LC) mixtures are measured from 300 GHz to 1500 GHz. Measurements are performed in a standard THz TDS setup. Refractive index and extinction coefficient for parallel and perpendicular orientation are calculated and compared to results obtained at 19 GHz. The investigated mixtures are of interest for Terahertz devices as their properties stay almost constant from 19 GHz to 1500 GHz.
