    Abstract: A RF generator includes a structure having an input section, an output section, and an opening extending between the input section and the output section, wherein the output section has a first cavity and a second cavity, and wherein the first and second cavities are spaced apart from each other so that they are electromagnetically uncoupled from each other. A method of providing RF energy, includes receiving an electron beam, providing a first RF energy through a first cavity, wherein the first RF energy is generated using the electron beam, and providing a second RF energy through a second cavity, wherein the second RF energy is generated using the electron beam, wherein the first cavity and the second cavity are spaced apart from each other so that they are electromagnetically uncoupled from each other.

    Abstract: An optically tunable cavity for an electronic device concurrently achieves high bandwidth (for example, at least about 10 percent, typically greater than about 50 percent) with high DC-RF efficiency (for example, at least about 50 percent, typically greater than about 85 percent). The electronic device may be a vacuum electronic device, including linear-beam and cross-field devices, with either an input circuit or an output circuit, or both, containing a photocapacitance-controlled resonator embedded such that a laser beam can impinge upon a semiconductor gap of the resonator. The laser beam may instantaneously change the resonant mode of the overall loaded cavity, thus allowing for amplification or oscillation of the desired frequency throughout the vacuum electronic device.

    Abstract: A solid state Klystron structure is fabricated by forming a source contact and a drain contact to both ends of a conducting wire and by forming a bias gate and a signal gate on the conducting wire. The conducting wire may be at least one carbon nanotube or at least one semiconductor wire with long ballistic mean free paths. By applying a signal at a frequency that corresponds to an integer multiple of the transit time of the ballistic carriers between adjacent fingers of the signal gate, the carriers are bunched within the conducting wire, thus amplifying the current through the solid state Klystron at a frequency of the signal to the signal gate, thus achieving a power gain.

    Abstract: A terahertz sheet beam klystron (TSBK) includes an electron gun configured to generate a sheet electron beam and a drift tube through which the sheet beam is propagated. The drift tube is provided with multiple resonant cavities and includes a drift tube circuit including an input RF circuit through which an input RF signal is introduced and an output RF circuit through which an output RF signal is extracted, a collector, and a vacuum envelope. The output RF circuit is configured such that Qe (extraction Q) of the drift tube circuit is comparable to Q0 (unloaded Q) of the drift tube circuit, thereby improving the efficiency of the drift tube circuit.
