The lens features a bilayer structure made of liquid crystal materials. Each layer responds differently to the applied electric field, splitting incoming light into oppositely polarized beams. Bifocal ...
Liquid crystals exist in a phase of their own. They can flow like liquids, but because their molecules are arranged in a somewhat orderly way, they can be easily manipulated to reflect light.
One notable class of these materials is lyotropic chromonic liquid crystals (LCLCs), which are molecular assemblies of amphiphilic π-electronic molecules, with water-absorbing and water-repelling ...
