Abstract: In described examples, a magnetic sensor includes a waveguide that encapsulates dipolar molecules. A mm-wave electromagnetic field is launched into the waveguide, travels through the dipolar molecules, and is then received after passing through the dipolar molecules. The frequency of the mm-wave electromagnetic signal is swept across a range that includes an intrinsic quantum rotational state transition frequency (Fr) for the dipolar molecules. Absorption peaks in accordance with the Zeeman effect are determined. A strength of a magnetic field affecting the magnetic sensor is proportional to a difference in the frequencies of the absorption peaks.

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: Millimeter wave energy is provided to a spectroscopy cavity of a spectroscopy device that contains interrogation molecules. The microwave energy is received after it traverses the spectroscopy cavity. The amount of interrogation molecules in the spectroscopy cavity is adjusted by activating a precursor material in one or more sub-cavities coupled to the spectroscopy cavity by a diffusion path to increase the amount of interrogation molecules or by activating the getter material in one or more sub-cavities coupled to the spectroscopy cavity by a diffusion path to decrease the amount of interrogation molecules.

Abstract: A clock apparatus includes: (a) a gas cell, including a continuous path cavity including a sealed interior for providing a signal waveguide; (b) an apparatus for providing an electromagnetic wave to travel along the continuous path cavity and for circulating around the continuous path cavity back toward and past a point of entry of the electromagnetic wave in the continuous path cavity; (c) a dipolar gas inside the sealed interior of the cavity; and (d) receiving apparatus for detecting an amount of energy in the electromagnetic wave, wherein the amount of energy is responsive to an amount of absorption of the electromagnetic wave as the electromagnetic wave passes through the dipolar gas.

Abstract: A method for forming a sealed cavity includes bonding a non-conductive structure to a first substrate to form a non-conductive aperture into the first substrate. On a surface of the non-conductive structure opposite the first substrate, the method includes depositing a first metal layer. The method further includes patterning a first iris in the first metal layer, depositing a first dielectric layer on a surface of the first metal layer opposite the non-conductive structure, and patterning an antenna on a surface of the first dielectric layer opposite the first metal layer. The method also includes creating a cavity in the first substrate, depositing a second metal layer on a surface of the cavity, patterning a second iris in the second metal layer, and bonding a second substrate to a surface of the first substrate opposite the non-conductive structure to thereby seal the cavity.
