Gradient-index Solar Sail and its Optimal Orbital Control
Shahin Firuzi, Yu Song, Shengping Gong
Solar sails with the capability of generating a tangential radiation pressure at the sun-pointing attitude, such as refractive sails can provide more efficient methods for attitude…
All-dielectric Tailored-index Index-matched Arbitrary Waveguides based on Transformation Optics
Shahin Firuzi, Shengping Gong
Transformation optics based on conformal mapping (CM) technique provides a practical approach to designing arbitrary-shaped all-dielectric devices. However, CM may result in large…
Long-range optical pulling force device based on vortex beams and transformation optics
Shahin Firuzi, Shengping Gong
In this work a method for generating a long-range optical pulling force is presented which is realized by utilizing a vortex beam and a device designed based on transformation opti…
On the Instability of Saturn's Hypothetical Retrograde Co-orbitals
Yukun Huang, Miao Li, Junfeng Li +1
We find an interesting fact that fictitious retrograde co-orbitals of Saturn, or small bodies inside the retrograde 1:1 resonance with Saturn, are highly unstable in our numerical…
Solar-Sail Trajectory Design for Multiple Near Earth Asteroid Exploration Based on Deep Neural Networks
Yu Song, Shengping Gong
In the preliminary trajectory design of the multi-target rendezvous problem, a model that can quickly estimate the cost of the orbital transfer is essential. The estimation of the…
Solar-Sail Deep Space Trajectory Optimization Using Successive Convex Programming
Yu Song, Shengping Gong
This paper presents a novel methodology for solving the time-optimal trajectory optimization problem for interplanetary solar-sail missions using successive convex programming. Bas…
