Abstract: The present disclosure provides methods and systems of generating high-efficiency structures for improved wireless communications. Such structures may comprise hard and chemically inert materials. Such structures may include materials having average thermal conductivities equal to or greater than about 1,000 W/mK. Such structures may comprise diamond. Such structures may comprise materials whose properties may be affected through processing such structures. Such structures may comprise devices with improved electron mobilities and efficiencies. Such structures may comprise substrate features. Such features may be configured to communicatively couple to a device or a component of a substrate. A device may comprise a radio transmitter. Some examples include satellite transmitters.
