    Conventional radiators for spacecraft usually consist of metal materials with their high reflectance for the solar light. However, they also simultaneously reflect radio waves and cannot be applied for the path of radio waves. Then, we have developed a new radio wave transmissive thermal control mirror, COSF (Controlled Optical Surface Film) which shows a low solar absorptance and a high total hemispherical emittance. This material is composed of dielectric multilayers on a polyimide film. The thickness of each layer is designed by genetic algorithm. The merit function is set to be a low solar absorptance and a high total hemispherical emittance. This paper presents a design method and measurement results about the thermo-optical properties of COSF.
