Vortex beams' orbital angular momentum (OAM) has important application value in optical communication and other fields. Accurate measurement of their OAM topological charges is required for the ...

When a vending-machine-sized spacecraft hit Dimorphos in 2022, planetary defense experts anticipated an easy test of kinetic ...

Recent findings confirm the conservation of orbital angular momentum in single-photon interactions, reinforcing fundamental ...

How does a planetary defense mission intended to push an asteroid off course manage to release a torrent of boulders with the same momentum as the spacecraft? NASA’s groundbreaking experiment, the ...

If Dassault Aviation has its way, it could be similar to its Véhicule Orbital Réutilisable de Transport et d’Exploration (VORTEX) reusable spaceplane unveiled at the recent Paris Air Show.

Dassault Unveils Vortex Spaceplane with ESA and French Military Support Reusable orbital vehicle could provide space station transport, cargo logistics, and in-orbit services for commercial ...

Dassault Aviation is exhibiting a small-scale model of the Vortex, a reusable spaceplane it is proposing for dual-use civil-military applications.

In addition, our study shows that the total angular momentum of the incident circularly polarized vortex beam can be conserved, where the far field of the transmitted beam contains both left- and ...
