摘要： A device is provided that includes a first waveguide configured to guide propagation of RF waves inside the first waveguide. A first side of the first waveguide is configured to emit an evanescent field associated with the propagation of the RF waves inside the first waveguide. The device also includes a second waveguide having a second side positioned within a predetermined distance to the first side of the first waveguide. The second waveguide is configured to guide propagation, inside the second waveguide, of induced RF waves associated with the evanescent field from the first waveguide. The device also includes a first probe coupled to the first waveguide and configured to emit the RF waves for propagation inside the first waveguide. The device also includes a second probe coupled to the second waveguide and configured to receive induced RF waves propagating inside the second waveguide.

摘要： A radio frequency rotary coupler with its power dividers/couplers separated among multiple circuit layers that are axially stacked and interconnected using coaxial feeds. This architecture allows for multiple layers of circuits with minimal outside diameter and while minimizing increase in axial length. The coupler includes a stator, rotor, and dynamic capacitive ring. The stator includes at least a first stator circuit layer with a primary stator power divider (SPD), a second stator circuit layer with at least one secondary SPD, and stator coaxial feeds coupling the primary SPD and the secondary SPD(s). The rotor includes a first rotor circuit layer with a primary rotor power divider (RPD), a second rotor circuit layer with at least one secondary RPD, and rotor coaxial feeds coupling the primary RPD and the secondary RPD(s). The dynamic capacitive ring couples the stator and the rotor via the secondary SPD(s) and RPD(s).

摘要： A high speed communication apparatus for a Computerized Axial Tomography (CAT) scanner utilizes large diameter slip rings to permit continuous rotation of a rotatable gantry. A communication signal is applied at a first point on one slip ring, and is terminated by a resistive termination point 180.degree. opposite the driving point. The communication signal may then be received at any point on the slip ring by a receive connection and a matching receive connection which are 180.degree. opposite one another. The drive and termination connections to the slip ring may be made by brushes, with the receive and matching receive connections being made by a physical connection to the slip ring. Alternately, the drive and terminate connections may be made by physical contact, with the receive and matching receive connections being made by brushes.

摘要： Disclosed is a rotating joint used in radars to transmit electrical signals on several channels between a rotating antenna and a fixed support. The pass-band of the matched and coupled circuits of each channel is substantially improved by making these circuits on concentric, circular rings which have metallic ground strips deposited on both faces, said strips being connected by metallized holes, and metallic strips of coils connected by the facing sections of the rings.
