Abstract: A method and an assembly for radio-frequency (RF) power coupling in a rack includes at least one box shaped power combiner and/or divider, connectors for inputting and outputting RF-power, conductors arranged inside the at least one box shaped power combiner and/or divider, electrically connecting the connectors with at least one center conductor, and at least one outside conductor formed as a box shaped casing.

Abstract: A device and a method for utilizing the device for radio-frequency (RF) power coupling, particularly a power combiner and/or divider, includes a box shaped casing forming the outside conductor, and connectors for inputting and outputting RF-power, which are electrically connected to at least one center conductor, where the electrical connection between the connectors and the at least one center conductor is a direct electrical and mechanical connection.

Abstract: An RF power combiner functioning as a higher-order harmonics filter comprises: at least one pair of coaxially arranged disc-shaped metal conductors, at least one of the conductors having a central axial opening to accommodate a waveguide is provided. Facing surfaces of the disk-shaped metal conductors are shaped symmetrically with respect to the plane of symmetry of the disk-shaped metal conductors to form a plurality of consecutive, radially communicating concentric cavities having isosceles trapezoids with different bases in section. The smaller base of each trapezoid disposed closer to the central axis. The number of the concentric cavities is (2 k+1), where K is the number of signal harmonics being filtered.

Abstract: This invention relates to a novel metallocene compound, a catalyst composition including the same and a method of preparing olefin-based polymers using the same. The use of the novel metallocene compound as a catalyst for preparing olefin-based polymers enables synthesis of an olefin-based polymer having a low molecular weight and a wide molecular weight distribution.

Abstract: A method for fabricating and the resulting x-ray target comprising metal deposited on an electrically-conductive base member by electrodeposition from a molten salt electrolyte is claimed. The method comprises submerging the base member in a molten salt electrolyte bath. The base member acts as a cathode and anodes of target material metals are activated by electrical circuitry to deposit a target layer onto the base member. The electrodeposition method results in an exceptionally dense and pure layer of tungsten or tungsten alloy. Target materials of tungsten, tungsten alloy, rhenium, and rhenium alloy produce good results when electrodeposited onto base members fabricated from molybdenum, molybdenum alloy, and graphite-or carbon-based composites.
