Self-Assembled Helical Slow-Wave Structures For High-Frequency Signals
Inventors: Max Lagally, Matthew Dwyer, Francesca Cavallo, Daniel van der Weide, Abhishek Bhat
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.
