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.

Abstract: A device includes a substrate that includes a resonant cavity. The resonant cavity includes a plurality of dipolar molecules that have an absorption frequency. The resonant cavity resonates at a frequency that is equal to the absorption frequency of the dipolar molecules. The device further includes a first port on the resonant cavity configured to receive a radio frequency (RF) signal.

Abstract: A pressure transducer includes a cavity, dipolar molecules disposed within the cavity, and pressure measurement circuitry. The pressure measurement circuitry is configured to measure a width of an absorption peak of the dipolar molecules, and to determine a value of pressure in the cavity based on the width of the absorption peak.

Abstract: A pressure transducer includes a cavity, a first dipolar molecule disposed within the cavity, and a second dipolar molecule disposed within the cavity. The first dipolar molecule exhibits a quantum rotational state transition at a fixed frequency with respect to cavity pressure. The second dipolar molecule exhibits a quantum rotation state transition at a frequency that varies with cavity pressure.
