Abstract： |
The disclosed electric field control light frequency negative refraction device, which comprises a polarizer, a LC, an electrode, and optical glass, is prepared as: coating polyimide on conductive surface of glass plate to solidify and form film, using fiber for orientated friction to obtain the conductive glass with LC molecule orientated along surface parallel sticking two glass plated with fiction surface opposite to form parallel electrode structure with mum-level distance fixing a polarizer above the upper electrode, and injecting LC into middle of electrodes. This invention shows negative refraction angle from -4.1deg to 0deg at 1.0-2.8V external voltage. |
