Abstract
We present an overview of the theoretical and experimental research activities at the U.S. Naval Research Laboratory in the area of millimeter-wave and sub-millimeter-wave vacuum electronics. Amplifier and related circuit development ranging in frequency from 30 GHz to 1.35 THz at power levels from multi-kilowatts to watts will be described along with electron gun topologies that include single-, multiple-, and sheet electron beams. We also describe new ultra-violet photolithographic techniques that enable the fabrication of thick (up to 1000 μm), high vertical aspect ratio, solid copper structures with integrated beam tunnels with length-to-diameter aspects ratios of <500.
