Reconfigurable Surfaces Using Fringing Electric Fields from Nanostructured Electrodes in Nematic Liquid Crystals

Liquid crystals with a varying phase profile enable reconfigurable and intelligent devices to be designed, which are capable of manipulating incident electromagnetic fields in display, telecommunications as well wearable applications. The active control defects these is becoming more important, especially since the electrodes used manipulate them shrinking nanometer length scales. In this paper, simple subwavelength, 1D, interdigitated metal electrode structure that can reconfigured using nematic liquid aligned homeotropic, planar, hybrid methods demonstrated. Accurate electro-optic modeling directors shown, induced by fringing electric fields. Applied voltages result crystal reorientation near bottom surface, such between electrodes. height does not affect lateral position defects. Rather, achieved increasing biasing voltage on top electrode, also leads greater splay-bend bulk material. These results therefore aim generalize complex anisotropic structures for range surface
