Abstract: An overmoded dielectric-lined waveguide, particularly for the 0.03 to 3 terahertz frequency range, is disclosed with performance advantages relative to prior dielectric-lined waveguides, cost and size advantages relative to corrugated waveguides, and with coupling, bandwidth, and cost advantages relative to micro-structured-fiber waveguides. The waveguide comprises a single-clad flexible microwave laminate rolled into a cylinder with said copper surface on an outside of said guide tube and said dielectric surface on an inside of said guide tube. The rolled laminate is supported inside a metal tube. The same method of achieving the structure needed for efficient guiding of HE11 mode may be applied to a conical tube to make a low-cost efficient overmoded tapered waveguide transition for the 0.03-3 THz range.

Abstract: A super-broadband waveguide feed network includes multiple receive (RX) full reject waveguide filters and multiple RX reject clone waveguide filters disposed in a clone carousel about an aperture port and configured to reject RX frequencies, and a branch line coupler configured to couple the multiple RX full reject waveguide filters and RX reject clone waveguide filters to other components of a waveguide feed network. The super-broadband waveguide feed includes an RX polarizer configured to couple to an end of the aperture port. The super-broadband waveguide feed is configured to be fabricated in one to three pieces composed of a single split plane on the zero-current region, and the super-broadband waveguide feed is circularly polarized.

Abstract: A vehicle having a communication system is disclosed. The system includes two electrical couplings, coupled by way of a rotary joint having a bearing waveguide. Each electrical coupling includes an interface waveguide configured to couple to external signals. Each electrical coupling also includes a waveguide section configured to propagate electromagnetic signals between the interface waveguide and the bearing waveguide of the rotary joint. Additionally, the rotary joint is configured to allow one electrical coupling to rotate with respect to the other electrical coupling. An axis of rotation of the rotary joint is defined by a center of a portion of the waveguides. Yet further, the rotary joint allows electromagnetic energy to propagate between the waveguides of the electrical couplings.

Abstract: A polarizer assembly including first and second components. The first component includes a first channel portion extending along a first component axis and having a plurality of first locking projections and/or first openings on opposite sides of the first channel portion. The second component includes a second channel portion extending along a second component axis and having a plurality of second locking projections and/or second openings on opposite sides of the second channel portion. The second component is rotatable relative to the first component about a common rotation axis between a pre-assembled position in which the second component axis is angularly offset from the first component axis, and an assembled position in which the second locking projections and/or second openings mate with the first locking projections and/or first openings and the first and second channel portions form a channel that functions to polarize waveforms.
