| titleOfInvention |
Traveling wave tube amplifier having a helical slow-wave structure supported by a cylindrical scaffold |
| abstract |
Traveling-wave tube amplifiers for high-frequency signals, including terahertz signals, and methods for making a slow-wave structure for the traveling-wave tube amplifiers are provided. The slow-wave structures include helical conductors that are self-assembled via the release and relaxation of strained films from a sacrificial growth substrate. |
