Disclosed are various embodiments for embedding data on a guided surface wave. A guided surface waveguide probe emits power as a guided surface wave received by a guided surface wave receive structure circuit. An aggregate electric load of the receiver circuit is modulated with reference to a data signal. A current at the guided surface waveguide probe is monitored. A data signal is recaptured at the guided surface waveguide probe.

A frequency modulation assembly includes a self-locking screw, a self-locking adjuster and an elastic member. The self-locking screw has a first external screw thread, the self-locking adjuster has a mounting hole in which an internal screw thread is formed, the self-locking screw is inserted into the mounting hole, and the first external screw thread is engaged with the internal screw thread to achieve a connection between the self-locking screw and the self-locking adjuster, one end of the self-locking screw which passes through the mounting hole is inserted into a ceramic resonance rod in the cavity filter, and the elastic member is connected with the self-locking screw and configured between the self-locking adjuster and the ceramic resonance rod. The frequency modulation assembly can decrease accumulated assembly tolerances, reduce manufacturing cost and improve assembly efficiency, further the elastic member is beneficial to adjust the accuracy of the frequency modulation effect.

The time delay of the photons emitted through the light path is substantially equivalent to the time delay of the electrical signal.
