Abstract
Disclosed are various embodiments for preventing theft of energy transmitted as a guided surface wave along the surface of a terrestrial medium, by pulsing the transmitted energy and protecting authorized devices from the pulse. In one embodiment, a guided surface wave receive structure is configured to obtain electrical energy from a guided surface wave. An electrical load coupled to the guided surface wave receive structure. The electrical load is experienced as a load at an excitation source coupled to a guided surface waveguide probe that is generating the guided surface wave with an electrical field strength that may be selectively increased. A pulse protection circuit is employed to selectively protect the electrical load from an increase in electrical energy received by the guided surface wave receive structure when the electrical field strength is selectively increased, while unprotected circuits may be damaged or disrupted by the pulse.
