Electromagnetic wave focusing device using shape memory polymer material and its mirror surface development and shape maintenance method

摘要

PPROBLEM TO BE SOLVED: To provide a method for making a reflector itself with super light weight and its support/development structure to be super light weight and realizing a development function by low power and a developed mirror surface curve maintenance function and to provide an electromagnetic wave converging device provided with such functions. PSOLUTION: In this electromagnetic wave converging device, polymeric materials having a shape storage function are adopted as its materials, and a designated shape is a thin plate in shape with a metal film applied to the surface of the thin plate. The electromagnetic wave focusing device maintains its folded state in a low temperature state and becomes its developed state in a high temperature state. The reflector factor of the surface of the electromagnetic wave converging device and the radiation rate of a rear surface are adjusted by coating to maintain the proper temperature of the electromagnetic wave converging device.
