摘要： One example includes a method for fabricating a substrate-integrated waveguide (SIW). The method includes forming a first metal layer on a carrier surface. The first metal layer can extend along an axis. The method also includes forming a first metal sidewall extending from a first edge of the first metal layer along the axis and forming a second metal sidewall extending from a second edge of the first metal layer opposite the first edge along the axis to form a trough extending along the axis. The method also includes providing a dielectric material over the first metal layer and over the first and second metal sidewalls. The method further includes forming a second metal layer over the dielectric material and over the first and second metal sidewalls. The second metal layer can extend along the axis to enclose the SIW in all radial directions along the axis.

摘要： In some examples, an apparatus comprises a substrate, an interposer mechanically coupled to the substrate, a gas cell on at least part of the interposer, and a plate on the gas cell and mechanically coupled to the interposer. Some examples of the apparatus are configured to be millimeter wave devices.

摘要： A physics cell includes a sealed glass vial that contains a high-purity dipolar gas (e.g., OCS) at a low pressure (e.g., between about 0.01 millibar and 0.2 millibar). The vial can be sealed using a laser cutting process that involves only local heating of the vial that does not denature the bulk of the contained gas. One or more electromagnetically translucent windows or vial-end access points provide access to electromagnetic waves launched or received by one or more electromagnetic antennas at a frequency that is adjusted to match the quantum transition frequency of the gas based on a detected maximum absorption frequency. The glass-vial physics cell can be fabricated at lower cost than physics cells fabricated from bonded wafers. Multiple vials can be joined by a waveguide in an enclosure so that launch and receive antennas can be provided at a single end of the vials.

摘要： A system is provided in which a set of modules each have a substrate on which is mounted a radio frequency (RF) transmitter and/or an RF receiver coupled to a near field communication (NFC) coupler located on the substrate. Each module has a housing that surrounds and encloses the substrate. The housing has a port region on a surface of the housing. Each module has a field confiner located between the NFC coupler and the port region on the housing configured to guide electromagnetic energy emanated from the NFC coupler through the port region to a port region of an adjacent module.
