abstract = "A multi-resonant unit cell composed of three unequal length parallel dipoles constructed on a liquid crystals (LC) substrate is designed operating within the frequency range from 97 to 102.36 GHz. An accurate modeling of the LC has been presented for the analysis of LC-based reconfigurable reflectarray cells. The proposed modeling gives the orientation of the LC molecules at each point in the LC layer under the electrostatic field considering the inhomogeneous and anisotropic effects. The threshold voltage and saturation voltage that cause LC molecular deflection obtained by this accurate modeling method are higher than 3 V and 30 V, respectively. The reflection loss of the unit cell is simulated and also compared with that of in the conventional model which usually assumes the LC is homogeneity and isotropy. The errors of phase range between these two models can exceed 280 which will seriously affect the common application, and then it is not negligible in the design.",
