Abstract: A system includes first and second gas cells each comprising a respective sealed interior waveguide; first transmit antenna coupled to the first gas cell to provide a first electromagnetic wave to the first gas cell along a first direction; second transmit antenna coupled to the first gas cell to provide a second electromagnetic wave to the first gas cell along a second direction opposite the first direction; third transmit antenna coupled to the second gas cell to provide a third electromagnetic wave to the second gas cell; first receive antenna coupled to the first gas cell to generate a first signal indicative of an amount of energy in first electromagnetic wave; second receive antenna coupled to the second gas cell to generate a second signal indicative of an amount of energy in second electromagnetic wave; and processor to calculate a background-free signal based on a difference between first and second signals.

Abstract: In one example, an apparatus includes a substrate, an antenna on the substrate, a sealed container enclosing a dipolar gas, a waveguide, and a stub. The waveguide is communicatively coupled between the antenna and the sealed container. The waveguide is separated from the substrate by a gap. The stub is adjacent to the waveguide and extends away from the gap.

Abstract: In some examples, a semiconductor package includes a semiconductor die; a conductive member coupled to the semiconductor die; and a multi-layer package substrate. The multi-layer package substrate includes a first horizontal metal layer to provide a ground connection; a second horizontal metal layer above the first horizontal metal layer; vertical members coupling to the first and second horizontal metal layers; and a mold compound covering the first and second horizontal metal layers and the vertical members. The first horizontal metal layer, the second horizontal metal layer, and the vertical members together form a structure including a conductive strip coupled to the conductive member, a transition member coupled to the conductive strip, a waveguide coupled to the transition member, and a horn antenna coupled to the waveguide.

Abstract: A quantum-based sensor includes a hollow electromagnetic (EM) waveguide having non-metallic layers and external metallic layers. The hollow EM waveguide encloses a gas having a pressure that is less than a threshold pressure, and all interior surfaces of the hollow EM waveguide in contact with the gas are non-metallic.

Abstract: A system includes first and second gas cells, each comprising a respective sealed interior waveguide. The first gas cell contains a dipolar gas and the second gas cell does not contain a dipolar gas. The system includes first and second transmit antennas coupled to the first and second gas cells, respectively, to provide first and second electromagnetic waves to the interior of the first and second gas cells, respectively; first receive antenna coupled to the first gas cell to generate a first signal indicative of an amount of energy in the first electromagnetic wave after travel through the first gas cell; second receive antenna coupled to the second gas cell to generate a second signal indicative of an amount of energy in the second electromagnetic wave after travel through the second gas cell; processor configured to calculate a background-free signal based on a difference between the first and second signals.
