Patent number: 11586075Abstract: A method for aligning molecular orientations of liquid crystals and/or polymeric materials into spatially variant patterns uses metamasks. When non-polarized or circularly polarized light is transmitted through or reflected by the metamasks, spatially varied polarization direction and intensity patterns of light can be generated. By projecting the optical patterns of the metamasks onto substrates coated with photoalignment materials, spatially variant molecular orientations encoded in the polarization and intensity patterns are induced in the photoalignment materials, and transfer into the liquid crystals. Possible designs for the metamask use nanostructures of metallic materials (e.g., rectangular nanocuboids of metallic materials arrayed on a transparent substrate).Type: GrantFiled: February 7, 2018Date of Patent: February 21, 2023Assignee: KENT STATE UNIVERSITYInventors: Qi-Huo Wei, Hao Yu, Yubing Guo, Miao Jiang, Oleg D.
