摘要： In one example, a method comprises filling a tube made of a same material with a dipolar gas; sealing a portion of the tube to form a container enclosing the dipolar gas. The method further comprises forming an electromagnetic reflective coating inside or outside the container, the electromagnetic reflective coating having an opening; and positioning an antenna at the opening.

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. An artificial magnetic conductor surface is positioned adjacent the backside of each NFC coupler to reflect back side electromagnetic energy with a phase shift of approximately zero degrees.
