CW 100 MW microwave power transfer in space [PDF]

open access: yesConference Record of the 1991 IEEE Particle Accelerator Conference, 2002
A proposal is made for high-power microwave transfer in space. The concept consists of a microwave power station integrating a multistage microwave free-electron laser (FEL) and an asymmetric dual-reflector system. Its use in space is discussed. A possible microwave power station operating at 17 GHz is depicted.
