Abstract

Liquid crystals are an attractive medium for millimetre-wave band communications devices due to their large birefringence and reconfigurability. However, characterizing these materials is challenging at these frequencies. This work details simulation tools that have been developed to aid in this process, through the accurate analysis of the liquid crystal orientation and wave propagation.
