Fabrication of Liquid Crystal Cells for Reconfigurable Microwave, Millimeter Wave and Terahertz Functional Devices

Liquid crystal cell is one of the essential elements in reconfigurable microwave, millimeter wave, and terahertz functional devices. Although liquid crystal display has matured, LCD technologies generally do not fit terahertz, millimeter wave, and microwave applications due to unique challenges arising from significant difference in frequency. In this chapter, a process for fabricating nematic liquid crystal cells for microwave, millimeter wave, and terahertz functional devices is presented. It is based on a xenomorphic substrate and solves the packaging and uniformity issues of large and thick nematic liquid crystal layer.
