DOI: 10.1016/j.actaastro.2019.12.013

Abstract: Abstract Electric sails are propulsion systems that generate momentum via the deflection of stellar wind particles through electric forces. Here, we investigate the relative merits of electric sails and light sails driven by stellar radiation… read more here.

DOI: 10.1021/acsphotonics.5c01886

Abstract: Laser-light sails are a spacecraft concept, wherein lightweight “sails” are propelled by high-intensity lasers. We investigated the near-infrared absorption of free-standing membranes of stoichiometric silicon nitride (Si3N4), a candidate sail material. To resolve the small… read more here.

DOI: 10.1364/ome.545481

Abstract: Deciding on appropriate materials and designs for use in light sails, like the one proposed in the Breakthrough Starshot Initiative, is a topic that requires much care and forethought. Here, we offer a feasible option… read more here.
