Tohoku Univ. Technology: Liquid Crystal Reflect Arrays for Electromagnetic Wave : T23-078
LC device eliminates coverage hole in millimeter wave communication
・ At millimeter wave communication, there is a concern about increasing coverage hole which is area where the communication becomes impossible. ・ Therefore, installing the reflect array for all over city that can control the direction of electromagnetic wave is proposed. ・ A conventional reflect array composed of liquid crystal (LC) has problem of slow response. ・ In the invention, reduction of response time is achieved by forming a stripe electrode on substrate which can be applied vertical and horizonal electric field. ・ The invention is not only expected to apply for reflect arrays, but also phase modulators and phased array antennas.
