| 摘要 |
A propulsion device 1 for use in an aerospace or other vehicle 2 comprises a first laser beam 11, a second laser beam 12 and a field material 13 which is a source of a first electric field. The first laser beam 11 and the second laser beam 12 are configured to interfere constructively within a superposition zone 16. The field material is located with respect to the superposition zone 16 such that a second electric field generated by the interference between the first laser beam 11 and the second laser beam 12 in the superposition zone 16 interacts with the first electric field to result in a force being applied to the field material 13. The field material 13 is configured for coupling to at least part of the vehicle 2 for movement therewith. |
