Abstract
In this chapter, a new perturbation method of double ridge waveguide resonator is proposed for microwave characterization of liquid crystals. It meets the requirements of accurately testing the dielectric anisotropy, dielectric tuning characteristics, dielectric loss, and required working frequency band of the microwave nematic liquid crystal. This method provides valuable information for understanding microwave nematic liquid crystals and further research and development of microwave nematic liquid crystal materials.
