Patents by Inventor Matthew McLean Dwyer

Matthew McLean Dwyer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electroplated helical slow-wave structures for high-frequency signals
    Patent number: 11588456
    Abstract: Traveling-wave tube amplifiers and methods for making slow-wave structures for the amplifiers are provided. The SWSs include helical conductors that are self-assembled via the release of stressed electrically conductive strips from a sacrificial material. The helical conductors can be electroplated post-self-assembly to fortify the helix, reduce losses, and tailor the dimensions and operating parameters of the helix.
    Type: Grant
    Filed: May 25, 2020
    Date of Patent: February 21, 2023
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Max G. Lagally, Matthew McLean Dwyer, Daniel Warren van der Weide, Abhishek Bhat, Francesca Cavallo, Divya Jyoti Prakash
  • SELF-ASSEMBLED HELICAL SLOW-WAVE STRUCTURES FOR HIGH-FREQUENCY SIGNALS
    Publication number: 20220044904
    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.
    Type: Application
