最近的液晶（LC）材料的表征总是使用磁场来偏置LC。本文提出了一种传输线方法，用于表征LC在60 GHz频段的介电性能，使用电场偏置。在该方法中，使用平衡带状线来容纳LC样品。为了便于电场的应用，以方便的LC和散射参数的测量，一个独特的过渡从平衡带线的有限接地共面波导（FGCPW）的开发。本文研究的LC是E7混合物。
Recent characterizations of liquid crystal (LC) materials invariably use magnetic field for biasing LC. In this paper a transmission line method is proposed for the characterization of the dielectric properties of LC in the 60 GHz band, using electric field bias. In this method a balanced strip line is used to accommodate the LC sample. To facilitate the application of the electric field to the LC and to ease the measurement of the scattering parameters, a unique transition from the balanced strip line to the finite ground coplanar waveguide (FGCPW) is developed. The LC investigated in this paper is the E7 mixture.
