Modelling and numerical optimisation of refractive surface patterns for transmissive solar sails (2025)
Journal Article
Thompson, S. M., Tuck, C., Pushparaj, N., & Cappelletti, C. (2025). Modelling and numerical optimisation of refractive surface patterns for transmissive solar sails. Acta Astronautica, 233, 99-112. https://doi.org/10.1016/j.actaastro.2025.03.039

Transmissive solar sail designs have been proposed with performance and utility benefits over traditional solar sails, particularly in low Earth orbit. The functional element of these new sails is their refractive or diffractive surface pattern. This...

Real-Time Contrail Monitoring and Mitigation Using CubeSat Constellations (2024)
Journal Article
Pushparaj, N., Cormier, L., Cappelletti, C., & Portapas, V. (2024). Real-Time Contrail Monitoring and Mitigation Using CubeSat Constellations. Atmosphere, 15(12), Article 1543. https://doi.org/10.3390/atmos15121543

Contrails, or condensation trails, left by aircraft, significantly contribute to global warming by trapping heat in the Earth’s atmosphere. Despite their critical role in climate dynamics, the environmental impact of contrails remains underexplored....
