Paper Abstract

Solar sailcrafts make use of radiation pressure to propel a payload through space. Modern diffractive structures such as broadband single order gratings, polarization diffraction gratings, and related metamaterials offer the potential to replace reflective sails with efficient diffractive sails for either solar or laser driven space travel. We have experimentally verified the radiation pressure force on a transmissive diffraction grating, demonstrating a large component of force parallel to the surface of the grating. This component is important for orbit-raising types of maneuvers. Unlike a reflective sail with force components only normal to the surface, we also measure a near-vanishing normal force component around the Littrow angle
