US Patent 11750236 Radio frequency waveguide communication in high temperature environments

A system includes a network of nodes. A controller of the system is operable to communicate with the network of nodes through one or more electromagnetic signals. A plurality of waveguides is configured to guide transmission of the one or more electromagnetic signals. A radio frequency transceiver is configured to establish communication between the controller and a first waveguide of the plurality of waveguides. A membrane is configured to support communication between the first waveguide and at least one node of the plurality of nodes.
