Abstract: An axially-fed RF power combiner combines a plurality of input signals to generate a single fundamental-mode transverse electromagnetic (TEM) output. The combiner comprises a vacuum coaxial transmission line having a plurality of coaxial vacuum feedthroughs configured to receive the input signals. The feedthroughs are arranged axially around the vacuum coaxial transmission line. An increasing gap is provided between the inner conductive surface and the outer conductive surface of the vacuum coaxial transmission line to gradually transition the input signals from each coaxial vacuum feedthrough to quasi-TEM mode signals within the vacuum envelope of the vacuum coaxial transmission line. In some conductive-ridge embodiments, the inner conductive surface of the vacuum coaxial transmission line may comprise a cylindrical conductive base and a plurality of radially-aligned conductive ridges azimuthally distributed within a vacuum envelope of the vacuum coaxial transmission line. In some ridge-less embodiments, the inner conductive surface includes a tapered region within the vacuum envelope to provide an increasing gap between the inner conductive surface and the outer conductive surface.

Abstract: An apparatus includes a capsule configured to be launched or carried towards an unmanned aerial vehicle (UAV). The apparatus also includes a directed energy device within or carried by the capsule. The directed energy device includes a first inductor configured to generate an inductive magnetic field that is able to inductively couple into one or more electronics of the UAV in order to disable or destabilize the UAV. The capsule can be configured to be launched towards the UAV and can include a loiter mechanism (such as a rotor, umbrella, or parachute) configured to maintain a position of the capsule or to slow a descent of the capsule after launch. The capsule can also be configured to be carried towards the UAV by a different UAV, and the apparatus can further include a tether coupling the capsule to the different UAV.

Abstract: An apparatus includes a containment vessel having an interior space configured to be sealed. The interior space is configured to receive at least one reservoir of liquid to be vaporized during a decontamination process. The apparatus also includes a base configured to be inserted into the interior space. The base is configured to receive one or more pieces of personal protection equipment to be heated and decontaminated within the interior space during the decontamination process. The base is configured to hold the one or more pieces of personal protection equipment above the at least one reservoir of liquid. The apparatus further includes a pressure-relief valve configured to be opened to release a pressure within the interior space. In some cases, the apparatus may include a filter configured to filter material passing through the pressure-relief valve.

Abstract: A high-power microwave (HPM) vacuum tube source and method of precise coaxial alignment of the field emission (FE) cathode, cylindrical RF generating tube and magnet field includes positioning a low-power thermionic emission (TE) cathode inside the FE cathode in a “cathode-in-cathode” arrangement. With the HPM source under vacuum and the FE cathode deactivated, the TE cathode emits a surrogate electron beam through the generating tube. Measurement circuits measure the surrogate electron beam's position with respect to a longitudinal axis fore and aft of the generating tube. The measurements circuits may, for example, be a repositionable fluorescent target or electric field sensors embedded in the cylindrical RF generating tube. The coaxial alignment of the primary cathode, cylindrical RE generating tube and magnet is adjusted until the position of the surrogate electron beam satisfies a coaxial alignment tolerance.
