| 摘要 |
The invention discloses systems and methods for mediating electromagnetic interaction with an RF wave in a TWT. Embodiments of the present invention can be employed in high power amplifiers in satellite transponders or radar systems. Embodiments of the invention extract RF power directly from a radioactive isotope (e.g. <SUP>238</SUP>Pu) by implementing a slow-wave structure in conjunction with the charged particles (e.g. alpha particles) from the isotope. In satellite applications, the invention can significantly reduce costs and mass by dramatically reducing the requirements of the supporting electrical power system.
