Paper Abstract

The refractive indices, and birefringence, of some common nematic liquid crystals are measured in the millimeter waves region mainly at 30 GHz. All liquid crystals measured had reasonably large birefringence in the range of 0.1 to 0.17. A proof of concept millimeter wave phase shifter was demonstrated based on magnetic field alignment of liquid crystal. Potential advantages of using liquid crystals in the millimeter wave range for device applications are discussed.
