    摘要： A slotted Substrate Integrated Air Waveguide (slotted SIAW) antenna array comprising a ground plane having a reflective planar surface formed of a conductive material; an air waveguide structure fixably attached to, or formed onto, the reflective surface of the ground plane and having a slotted aperture defined, in part, by two conductive side walls that terminates at a conductive end wall, where a portion of the conductive side walls and a portion of the conductive end wall define an aperture-facing radiative conductive surface of the aperture and electrically couples with a conductive antenna feedline; and a slotted cover plate fixably attached to, or formed onto, the slotted-waveguide structure and having an area that fully covers the slotted aperture and has two or more radiating slotted apertures coincident to the slotted aperture and to the reflective planar surface of the ground plane.

    摘要： Techniques for implementing series-fed antenna arrays with a variable dielectric waveguide. In one implementation, coupling elements with optional controlled phase shifters are placed adjacent each radiating element of the array. To avoid frequency sensitivity of the resulting array, one or more waveguides have a variable propagation constant. The variable waveguide may use certain materials exhibiting this phenomenon, or may have configurable gaps between layers. Plated-through holes and pins can control the gaps; and/or a 2-D circular or a rectangular travelling wave array of scattering elements can be used as well.

    摘要： An apparatus for separating ions having different mass or charge includes a waveguide conduit coupled to a microwave source for transmitting microwaves through openings in the waveguide conduit. The outlet ends of pipes are positioned at the openings for transporting material from a material source to the openings. A plasma chamber is in communication with the waveguide tube through the openings. The plasma chamber receives through the openings microwaves from the waveguide tube and material from the pipes. The plasma chamber includes magnets disposed in an outer wall thereof for forming a magnetic field in the plasma chamber. The plasma chamber includes a charged cover at a side of the chamber opposite the side containing the openings. The cover includes extraction holes through which ion beams from the plasma chamber are extracted. Deflectors coupled to one of the extraction holes receive the ion beams extracted from the plasma chamber. Each deflector bends an ion beam and provides separate passages for capturing ions following different trajectories from the bending of the ion beam based on their respective mass or charge.
