According to some embodiments, an apparatus includes a circuit board made of polycrystalline diamond. The circuit board is formed by thermolysis of layers of a preceramic polymer. A plurality of tubes are formed within the circuit board and comprise a plurality of terminations at one or more surfaces of the circuit board. Each tube comprises a layer of graphene that is operable to permit each tube to conduct electrical current. Each layer of graphene is formed by thermolysis of the polycrystalline diamond circuit board at a temperature greater than or equal to 900 degrees Celsius. The apparatus also includes a plurality of optical waveguides formed within the circuit board. Each optical waveguide comprises a core of polycrystalline silicon carbide surrounded by polycrystalline diamond. The polycrystalline diamond is formed by thermolysis of poly(hydridocarbyne) and the silicon carbide is formed by thermolysis of poly(methylsilyne).

Abstract:
The present disclosure provides a millimeter-wave waveguide communication system. The millimeter-wave waveguide communication system may comprise: a clock component, and at least two sets of millimeter-wave receiving/transmitting channels. The clock component is configured to provide a clock signal to sending ends and receiving ends of the two sets of millimeter-wave receiving/sending channels respectively. Each set of millimeter-wave receiving/sending channels comprises: a transmitter component, a receiver component and a transmission waveguide. The transmission waveguide is located between the transmitter component and the receiver component and is configured to provide a channel for millimeter-wave transmission. The top face, side face and/or bottom face of the transmission waveguide, except for active devices and accessories thereof, are plated with a metal conductive wall to form an electromagnetic shield from a transmission waveguide in an adjacent millimeter-wave receiving/sending channel. The metal conductive wall can minimize the crosstalk between the channels during high-speed communications, thereby improving data bandwidth and data throughput of the millimeter-wave communication system.

Abstract:
A method and stiffener-embedded waveguide structure are provided for implementing enhanced data transfer for printed circuit board applications. At least one microwave channel is defined within a stiffener. The microwave channel provides a high frequency path for data transfers. Use of the waveguide channel in the stiffener for data transfers can replace or supplement otherwise required transmission paths in an associated printed circuit board.
