  "abstract": "We have designed a thin 3-layer sun-facing diffractive Bragg reflector comprised of a chiral polymeric liquid crystal film. Using Rigorous Coupled-Wave Analysis (RCWA), the stack was optimized to maximize the transverse radiation pressure force across the wavelength band 0.47 - 1.67 micrometers. The optimized structure operates on a single polarization state of light. A two structure stack, each operating on a different state of polarization, is predicted to provide a transverse momentum transfer efficiency of 51%. This study demonstrates how a wavelength selective Bragg grating may be used both as a sunshade to scatter sunlight away from the Earth, and as a solar sail for maintaining a prescribed orbit (such as the Earth-Sun L1 point) owing to the momentum transfer efficiency.",
