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.

Abstract: In a described example, an apparatus includes a first substrate having a first side, a second side, and a coupling interface across a portion of the first side. The coupling interface including an arrangement of subwavelength periodic structures formed in the first substrate. A second substrate is coupled to a portion of the second side of the first substrate to form a sealed cavity aligned with the coupling interface.

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.

Abstract: A clock generator includes a hermetically sealed cavity and clock generation circuitry. A dipolar molecule in the hermetically sealed cavity has a quantum rotational state transition at a fixed frequency. The clock generation circuitry generates an output clock signal based on the fixed frequency of the dipolar molecule. The clock generation circuitry includes a detection circuit, a reference oscillator, and control circuitry. The detection circuit generates a first detection signal and a second detection signal representative of amplitude of signal at an output of the hermetically sealed cavity responsive to a first sweep signal and a second sweep signal input to the hermetically sealed cavity. The control circuitry sets a frequency of the reference oscillator based on a difference in time of identification of the fixed frequency of the dipolar molecule in the first detection signal and the second detection signal.

Abstract: Methods for depositing a measured amount of a species in a sealed cavity. In one example, a method for depositing molecules in a sealed cavity includes depositing a selected number of microcapsules in a cavity. Each of the microcapsules contains a predetermined amount of a first fluid. The cavity is sealed after the microcapsules are deposited. After the cavity is sealed the microcapsules are ruptured to release molecules of the first fluid into the cavity.

Abstract: An illustrate method (and device) includes etching a cavity in a first substrate (e.g., a semiconductor wafer), forming a first metal layer on a first surface of the first substrate and in the cavity, and forming a second metal layer on a non-conductive structure (e.g., glass). The method also may include removing a portion of the second metal layer to form an iris to expose a portion of the non-conductive structure, forming a bond between the first metal layer and the second metal layer to thereby attach the non-conductive structure to the first substrate, sealing an interface between the non-conductive structure and the first substrate, and patterning an antenna on a surface of the non-conductive structure.
