Abstract
A new class of efficient vacuum electronic devices (VEDs) for THz wave generation and amplification are disclosed. The EM circuits of these VEDs are micro-fabricated from Si wafers with high precision. The original design of the EM circuits overcomes the main limitations of existing THz VEDs constructed from metal or metallized components, such as low fabrication precision, high signal losses, low tolerance to electric breakdown and low beam efficiency. The disclosed VEDs may have up to 50% beam efficiency in the THz band.
Claims22
A vacuum electronic device for terahertz wave generation or amplification, comprising:
- a vacuum enclosure containing:
- a cathode and an anode for generating an electron beam;
- a dielectric ribbon waveguide in close proximity to the electron beam;
- wherein the dielectric ribbon waveguide is configured to operate at a mode to generate an electric field extending beyond its surfaces to interact with the electron beam to amplify or generate terahertz energy;
- and
- an antenna or interconnect for transmitting the terahertz energy out of the vacuum enclosure.
A vacuum electronic device for terahertz wave generation or amplification, comprising:
- a vacuum enclosure containing:
- a cathode and an anode for generating an electron beam;
- more than one dielectric ribbon waveguide in close proximity to the electron beam;
- wherein the more than one dielectric ribbon waveguide is configured to operate at a mode to generate an electric field extending beyond its surfaces to interact with the electron beam to amplify or generate terahertz energy;
- and
- an antenna or interconnect for transmitting the terahertz energy out of the vacuum enclosure.
