Abstract
Systems and methods are described for producing liquid crystal devices microwave that use metal alignment layers. The liquid crystal microwave devices include a liquid crystal layer sandwiched between metal layers, which are further sandwiched between substrate layers. At least one of the metal layers is rubbed to form micro-grooves that tend to align the liquid crystal molecules adjacent to those layers without using additional rubbed polymeric layers for the alignment. The thickness of the metal layers can be selected to yield a desired electromagnetic effect, such as constraint of propagation of microwave radiation.
